I have a computer with a 4070 super with 12GB and flux fp8 simple wokflow take about ~40 seconds. With a 4090 in the cloud I can run flux fp16 in ~12 seconds. (There are of course also some workflow that I can't even run locally.) My referal link for Runpod : (If you use that i will have a commission, at no extra cost for you.) If you want to use my nodes and comfyui in the cloud (and can install more stuff), I'm managing an optimized ready-to-use template on runpod : Template name : `bjornulf-comfyui-allin-workspace`, can be operational in ~3 minutes. (Depending on your pod, setup and download of extra models or whatever not included.) You need to create and select a network volume before using that, size is up to you, i have 50Gb Storage because i use cloud only for Flux or lora training on a 4090. (~0.7$/hour) ⚠️ When pod is ready, you need to open a terminal in browser (After clicking on `connect` from your pod) and use this to launch ComfyUI manually : `cd /workspace/ComfyUI && python main.py --listen 0.0.0.0 --port 3000` or the alias `start_comfy` (Much better to control it with a terminal, check logs, etc...) After that you can just click on the `Connect to port 3000` button. As file manager, you can use the included `JupyterLab` on port 8888. If you have any issues with it, please let me know. It will manage everything in Runpod network storage (`/workspace/ComfyUI`), so you can stop and start the cloud GPU without losing anything, change GPU or whatever. Zone : I recommend `EU-RO-1`, but up to you. Top-up your Runpod account with minimum 10$ to start. ⚠️ Warning, you will pay by the minute, so not recommended for testing or learning comfyui. Do that locally !!! Run cloud GPU only when you already have your workflow ready to run. Advice : take a cheap GPU for testing, downloading models or settings things up. To download checkpoint or anything else, you need to use the terminal. For downloading from Huggingface (get token here ). Here is example for everything you need for flux dev : ``` huggingface-cli login --token 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 huggingface-cli download black-forest-labs/FLUX.1-dev flux1-dev.safetensors --local-dir /workspace/ComfyUI/models/unet huggingface-cli download comfyanonymous/flux_text_encoders clip_l.safetensors --local-dir /workspace/ComfyUI/models/clip huggingface-cli download comfyanonymous/flux_text_encoders t5xxl_fp16.safetensors --local-dir /workspace/ComfyUI/models/clip huggingface-cli download black-forest-labs/FLUX.1-dev ae.safetensors --local-dir /workspace/ComfyUI/models/vae ``` To use Flux you can just drag and drop in your browser comfyui interface the .json from my github repo : `workflows/FLUX_dev_troll.json`, direct link : . For downloading from civitai (get token here ), just copy/paste the link of checkpoint you want to download and use something like that, with your token in URL : ``` CIVITAI="8b275fada679ba5812b3da2bf35016f6" wget --content-disposition -P /workspace/ComfyUI/models/checkpoints "https://civitai.com/api/download/models/272376?type=Model&format=SafeTensor&size=pruned&fp=fp16&token=$CIVITAI" ``` If you want to download for example the entire output folder, you can just compress it : ``` cd /workspace/ComfyUI/output && tar -czvf /workspace/output.tar.gz . ``` Then you can download it from the file manager JupyterLab. If you have any issues with this template from Runpod, please let me know, I'm here to help. 😊 # πŸ— Dependencies (nothing to do for runpod ☁) Check `requirements.txt` for the latest dependencies... ## πŸͺŸπŸ Windows : Install dependencies on windows with embedded python (portable version) First you need to find this python_embedded `python.exe`, then you can right click or shift + right click inside the folder in your file manager to open a terminal there. This is where I have it, with the command you need : `H:\ComfyUI_windows_portable\python_embeded> .\python.exe -m pip install pydub ollama opencv-python` When you have to install something you can retake the same code and install the dependency you want : `.\python.exe -m pip install whateveryouwant` You can then run comfyui. ## 🐧🐍 Linux : Install dependencies (without venv, not recommended) Move to the custom_node folder and do : `pip install -r requirements.txt` OR - `pip install ollama` (you can also install ollama if you want : https://ollama.com/download) - You don't need to really install it if you don't want to use my ollama node. (BUT you need to run `pip install ollama`) - `pip install pydub` (for TTS node) - `pip install opencv-python` - etc... ## 🐧🐍 Linux : Install dependencies with python virtual environment (venv) If you want to use a python virtual environment only for comfyUI, which I recommended, you can do that for example (also pre-install pip) : ``` sudo apt-get install python3-venv python3-pip python3 -m venv /the/path/you/want/venv/bjornulf_comfyui ``` Once you have your environment in this new folder, you can activate it with and install dependencies inside : ``` source /the/path/you/want/venv/bjornulf_comfyui/bin/activate cd custom_nodes/Bjornulf_custom_nodes pip install -r requirements.txt ``` Then you can start comfyui with this environment (notice that you need to re-activate it each time you want to launch comfyui) : ``` cd /where/you/installed/ComfyUI && python main.py ``` # πŸ“ Changelog - **v0.2**: Improve ollama node with system prompt + model selection. - **v0.3**: Add a new node : Save image to a chosen folder. - **v0.3**: Add comfyui Metadata / workflow to all my image-related nodes. - **v0.4**: Support transparency option with webm format, options encoders.

Fix a lot of code everywhere, a little better logging system, etc... WIP : Rewrite of all my ffmpeg nodes. (Still need improvements and fixes, will do that in 0.71?) Maybe don't use them yet... - **0.71**: ❗Breaking changes for Global variable nodes. (add to global variable system a "filename", which is a a separate global variable file.) bug fix speech to text node, 5 new nodes 129-133. combine text limit raised to 100. improve Save image in folder node. - **0.71-0.75**: Many bug fixing. Civitai nodes are working on windows. (encoding, links problem are solved ? - at least on my machines...) - **0.76**: Removed kokoro_onnx from requirements.txt due to sonflict with other nodes (need to be installed manually if you want to use this node.) New syntaxes for advanced text/line selector, ex: {left|right|middle|group=LMR}+{left|right|middle|group=LMR}+{left|right|middle|group=LMR} and {A(80%)|B(15%)|C(5%)} 2 new nodes switch : πŸ”›βœ¨ Anything Switch On/Off (compatible with combine images) AND πŸ”›πŸ“ Text Switch On/Off (Compatible with combine texts) 2 new pick Me global nodes, using an identifier instead of chain : πŸŒŽβœ’πŸ‘‰ Global Write Pick Me AND 🌎πŸ“₯ Load Global Pick Me 3 random nodes : 🌎🎲 Global Random Seed, 🎲 Random Integer, 🎲 Random Float (Each return their value but also TEXT version of it.) "Seed node" more advanced. 1 new node to quickly select element from list : πŸ“‘πŸ‘ˆ Select from List 1 new audio node : πŸ”Šβ–Ά Play Audio (Just play an audio file, will default to bell.m4a if none provided.) Can take AUDIO format or audio_path. ❗Breaking changes. Large rewrite for all FFMPEG related nodes. With options for video preview. (Still have few changes to make, next version.) # πŸ“ Nodes descriptions ## 1 - πŸ‘ Show (Text, Int, Float) **Description:** The show node will only display text, or a list of several texts. (read only node) 3 types are managed : Green is for STRING type, Orange is for FLOAT type and blue is for INT type. I put colors so I/you don't try to edit them. 🀣 Update 0.61 : You now also have 4 other nodes to display format specific values : INT, FLOAT, STRING and JSON (STRING) These are convenient because these are automatically recommended on drag and drop. ![Show Text](screenshots/show.png) ## 2 - βœ’ Write Text **Description:** Simple node to write text. ![write Text](screenshots/write.png) ## 3 - βœ’πŸ—”πŸ…°οΈ Advanced Write Text (+ 🎲 random option) **Description:** Advanced Write Text node allows for special syntax to accept random variants, like `{hood|helmet}` will randomly choose between hood or helmet. You also have `seed` and `control_after_generate` to manage the randomness. It is also displaying the text in the comfyui console. (Useful for debugging) Example of console logs : ``` Raw text: photo of a {green|blue|red|orange|yellow} {cat|rat|house} Picked text: photo of a green house ``` ![write Text Advanced](screenshots/write_advanced.png) You can also create and reuse variables with this syntax : ``. Usage example : ![variables](screenshots/variables.png) ❗ 0.76 - New syntax available : Groups, with no duplicate, example : {left|right|middle|group=LMR}+{left|right|middle|group=LMR}+{left|right|middle|group=LMR} Random based on percentage : {A(80%)|B(15%)|C(5%)} ## 4 - πŸ”— Combine Texts **Description:** Combine multiple text inputs into a single output. (can have separation with : comma, space, new line or nothing.) ![Combine Texts](screenshots/combine_texts.png) ## 5 - 🎲 Random (Texts) **Description:** Generate and display random text from a predefined list. Great for creating random prompts. You also have `control_after_generate` to manage the randomness. ![Random Text](screenshots/random_text.png) ## 6 - β™» Loop **Description:** General-purpose loop node, you can connect that in between anything. ![Loop](screenshots/loop.png) It has an optional input, if no input is given, it will loop over the value of the STRING "if_no_input" (take you can edit). ❗ Careful this node accept everything as input and output, so you can use it with texts, integers, images, mask, segs etc... but be consistent with your inputs/outputs. Do not use this Loop if you can do otherwise. This is an example together with my node 28, to force a different seed for each iteration : ![Loop](screenshots/loop4.png) ## 7 - β™» Loop Texts **Description:** Cycle through a list of text inputs. ![Loop Texts](screenshots/loop_texts.png) Here is an example of usage with combine texts and flux : ![Loop Texts example](screenshots/loop_text_example.png) ## 8 - β™» Loop Integer **Description:** Iterate through a range of integer values, good for `steps` in ksampler, etc... ![Loop Integer](screenshots/loop_integer.png) ![Loop Int + Show Text](screenshots/loop_int+show_text.png) ❗ Don't forget that you can convert ksampler widgets to input by right-clicking the ksampler node : ![Widget to Input](screenshots/widget-to-input.png) Here is an example of usage with ksampler (Notice that with "steps" this node isn't optimized, but good enough for quick testing.) : ![Widget to Input](screenshots/example_loop_integer.png) ## 9 - β™» Loop Float **Description:** Loop through a range of floating-point numbers, good for `cfg`, `denoise`, etc... ![Loop Float + Show Text](screenshots/loop_float+show_text.png) ![Loop Float](screenshots/loop_float.png) Here is an example with controlnet, trying to make a red cat based on a blue rabbit : ![Loop All Samplers](screenshots/loop_float_example.png) ## 10 - β™» Loop All Samplers **Description:** Iterate over all available samplers to apply them one by one. Ideal for testing. ![Loop All Samplers](screenshots/loop_all_samplers.png) Here is an example of looping over all the samplers with the normal scheduler : ![Loop All Samplers](screenshots/example_loop_all_samplers.png) ## 11 - β™» Loop All Schedulers **Description:** Iterate over all available schedulers to apply them one by one. Ideal for testing. (same idea as sampler above, but for schedulers) ![Loop All Schedulers](screenshots/loop_all_schedulers.png) ## 12 - β™» Loop Combos **Description:** Generate a loop from a list of my own custom combinations (scheduler+sampler), or select one combo manually. Good for testing. ![Loop Combos](screenshots/loop_combos.png) Example of usage to see the differences between different combinations : ![example combos](screenshots/example_combos.png) ## 13/14 - πŸ“ + πŸ–Ό Resize and Save Exact name βš οΈπŸ’£ **Description:** Resize an image to exact dimensions. The other node will save the image to the exact path. βš οΈπŸ’£ Warning : The image will be overwritten if it already exists. ![Resize and Save Exact](screenshots/resize_save_exact.png) ## 15 - πŸ’Ύ Save Text **Description:** Save the given text input to a file. Useful for logging and storing text data. If the file already exist, it will add the text at the end of the file. I recommend you to keep saving them in "Bjornulf/Text" (Which is in the Comfyui folder, next to output), this is where the node 116 `Load text from folder` is looking for text files. ![Save Text](screenshots/save_text.png) ## 16 - πŸ’ΎπŸ–ΌπŸ’¬ Save image for Bjornulf LobeChat (❗For my custom [lobe-chat](https://github.com/justUmen/Bjornulf_lobe-chat)❗) **Description:** ❓ I made that node for my custom lobe-chat to send+receive images from Comfyui API : [lobe-chat](https://github.com/justUmen/Bjornulf_lobe-chat) It will save the image in the folder `output/BJORNULF_LOBECHAT/`. The name will start at `api_00001.png`, then `api_00002.png`, etc... It will also create a link to the last generated image at the location `output/BJORNULF_API_LAST_IMAGE.png`. This link will be used by my custom lobe-chat to copy the image inside the lobe-chat project. ![Save Bjornulf Lobechat](screenshots/save_bjornulf_lobechat.png) ## 17 - πŸ’ΎπŸ–Ό Save image as `tmp_api.png` Temporary API βš οΈπŸ’£ **Description:** Save image for short-term use : ./output/tmp_api.png βš οΈπŸ’£ ![Save Temporary API](screenshots/save_tmp_api.png) ## 18 - πŸ’ΎπŸ–ΌπŸ“ Save image to a chosen folder name **Description:** Save image in a specific folder : `my_folder/00001.png`, `my_folder/00002.png`, etc... Also allow multiple nested folders, like for example : `animal/dog/small`. ![Save Temporary API](screenshots/save_image_to_folder.png) ## 19 - πŸ¦™πŸ’¬ Ollama Talk **Description:** Use Ollama inside Comfyui. (Require the backend Ollama to be installed and currently running.) Use by default the model `llama3.2:3b` and the URL `http://0.0.0.0:11434`. (For custom configuration, use node 63) Example of basic usage : ![Ollama](screenshots/1_ollama_basic.png) Example of usage with context, notice that with context you can follow up a conversation, "there" is clearly understood as "Bucharest" : ![Ollama](screenshots/2_ollama_context.png) You can also use `use_context_file` (set to True), this will save the context in a file : `ComfyUI/Bjornulf/ollama_context.txt`. This way you can keep using the context without having to connect many nodes connected to each other, just run the same workflow several times. ### Example in 3 steps of context file conversation Step 1 : Notice that for now context is empty, so it will be the first message in `ComfyUI/Bjornulf/ollama_context.txt` : ![Ollama](screenshots/3_ollama_contextFile_1.png) Step 2 : Notice that now the number of lines in context file has changed (These are the same as the `updated_context`): ![Ollama](screenshots/3_ollama_contextFile_2.png) Step 3 : Notice that the number of lines keep incrementing. ![Ollama](screenshots/3_ollama_contextFile_3.png) When clicking the `reset Button`, it will also save the context in : `ComfyUI/Bjornulf/ollama_context_001.txt`, `ComfyUI/Bjornulf/ollama_context_002.txt`, etc... ⚠️ If you want to have an "interactive" conversation, you can enable the option `waiting_for_prompt`. When set to True, it will create a `Resume` button, use this to unpause the node and process the prompt. ### Example in 3 steps of waiting_for_prompt interactive conversation Step 1: I run the workflow, notice that Show node is empty, the node is pausing the workflow and is waiting for you to edit the prompt. (Notice that at this moment, it is asking for the capital of France.) ![Ollama](screenshots/ollama_waiting_1.png) Step 2: I edit the prompt to change France into China, but the node won't process the request until you click on Resume. ![Ollama](screenshots/ollama_waiting_2.png) Step 3: I click on Resume button, this is when the request is done. Notice that it used China and not France. ![Ollama](screenshots/ollama_waiting_3.png) Other options : - You also have `control_after_generate` to force the node to rerun for every workflow run. (Even if there is no modification of the node or its inputs.) - You can set `max_tokens` to reduce the size of the answer, a token is about 3 english characters. - You can force the answer to be on a single line, can be useful. - You have the option to keep the mode in VRAM. (If you plan having to generate many times with the same prompt) - Each run will be significantly faster, but not free your VRAM for something else. ⚠️ Warning : Using `vram_retention_minutes` might be a bit heavy on your VRAM. Think about if you really need it or not. Most of the time, when using `vram_retention_minutes`, you don't want to have also a generation of image or anything else in the same time. ## 20 - πŸ“Ή Video Ping Pong **Description:** Create a ping-pong effect from a list of images (from a video) by reversing the playback direction when reaching the last frame. Good for an "infinity loop" effect. ![Video Ping Pong](screenshots/video_pingpong.png) ## 21 - πŸ–ΌβžœπŸ“Ή Images to Video (FFMPEG Save Video) **Description:** Combine a sequence of images into a video file. ![Images to Video](screenshots/imgs2video.png) ❓ I made this node because it supports transparency with webm format. (Needed for rembg) Temporary images are stored in the folder `ComfyUI/temp_images_imgs2video/` as well as the wav audio file. ## 22 - πŸ”² Remove image Transparency (alpha) **Description:** Remove transparency from an image by filling the alpha channel with a solid color. (black, white or greenscreen) Of course it takes in an image with transparency, like from rembg nodes. Necessary for some nodes that don't support transparency. ![Remove Alpha](screenshots/remove_alpha.png) ## 23 - πŸ”² Image to grayscale (black & white) **Description:** Convert an image to grayscale (black & white) ![Image to Grayscale](screenshots/grayscale.png) Example : I sometimes use it with Ipadapter to disable color influence. But you can sometimes also want a black and white image... ## 24 - πŸ–Ό+πŸ–Ό Stack two images (Background + Overlay) **Description:** Stack two images into a single image : a background and one (or several) transparent overlay. (allow to have a video there, just send all the frames and recombine them after.) ![Superpose Images](screenshots/combine_background_overlay.png) Update 0.11 : Add option to move vertically and horizontally. (from -50% to 150%) ❗ Warning : For now, `background` is a static image. (I will allow video there later too.) ⚠️ Warning : If you want to directly load the image with transparency, use my node `πŸ–Ό Load Image with Transparency β–’` instead of the `Load Image` node. ## 25 - πŸŸ©βžœβ–’ Green Screen to Transparency **Description:** Transform greenscreen into transparency. Need clean greenscreen ofc. (Can adjust threshold but very basic node.) ![Greenscreen to Transparency](screenshots/greeenscreen_to_transparency.png) ## 26 - 🎲 Random line from input **Description:** Take a random line from an input text. (When using multiple "Write Text" nodes is annoying for example, you can use that and just copy/paste a list from outside.) You can change fixed/randomize for `control_after_generate` to have a different text each time you run the workflow. (or not) ![Random line from input](screenshots/random_line_from_input.png) ## 27 - β™» Loop (All Lines from input) **Description:** Iterate over all lines from an input text. (Good for testing multiple lines of text.) ![Loop input](screenshots/loop_all_lines.png) ## 28 - πŸ”’ Text with random Seed **Description:** ❗ This node is used to force to generate a random seed, along with text. But what does that mean ??? When you use a loop (β™»), the loop will use the same seed for each iteration. (That is the point, it will keep the same seed to compare results.) Even with `randomize` for `control_after_generate`, it is still using the same seed for every loop, it will change it only when the workflow is done. Simple example without using random seed node : (Both images have different prompt, but same seed) ![Text with random Seed 1](screenshots/random_seed_1.png) So if you want to force using another seed for each iteration, you can use this node in the middle. For example, if you want to generate a different image every time. (aka : You use loop nodes not to compare or test results but to generate multiple images.) Use it like that for example : (Both images have different prompt AND different seed) ![Text with random Seed 2](screenshots/random_seed_2.png) Here is an example of the similarities that you want to avoid with FLUX with different prompt (hood/helmet) but same seed : ![Text with random Seed 3](screenshots/random_seed_3_flux.png) Here is an example of the similarities that you want to avoid with SDXL with different prompt (blue/red) but same seed : ![Text with random Seed 4](screenshots/random_seed_4_sdxl.png) FLUX : Here is an example of 4 images without Random Seed node on the left, and on the right 4 images with Random Seed node : ![Text with random Seed 5](screenshots/result_random_seed.png) ## 29 - πŸ–Ό Load Image with Transparency β–’ **Description:** Load an image with transparency. The default `Load Image` node will not load the transparency. ![Load image Alpha](screenshots/load_image_alpha.png) ## 30 - πŸ–Όβœ‚ Cut image with a mask **Description:** Cut an image from a mask. ![Cut image](screenshots/image_mask_cut.png) ## 31 - πŸ”Š TTS - Text to Speech (100% local, any voice you want, any language) **Description:** Use my TTS server to generate high quality speech from text, with any voice you want, any language. [Listen to the audio example](https://github.com/user-attachments/assets/5a4a67ff-cf70-4092-8f3b-1ccc8023d8c6) ![TTS](screenshots/tts.png) ❗ Node never tested on windows, only on linux for now. ❗ Use my TTS server to generate speech from text, based on XTTS v2. ❗ Of course to use this comfyui node (frontend) you need to use my TTS server (backend) : I made this backend for , but you can use it with comfyui too with this node. After having `Bjornulf_XTTS` installed, you NEED to create a link in my Comfyui custom node folder called `speakers` : `ComfyUI/custom_nodes/Bjornulf_custom_nodes/speakers` That link must be a link to the folder where you installed/stored the voice samples you use for my TTS, like `default.wav`. If my TTS server is running on port 8020 (You can test in browser with the link ) and voice samples are good, you can use this node to generate speech from text. **Details** This node should always be connected to a core node : `Preview audio`. My node will generate and save the audio files in the `ComfyUI/Bjornulf_TTS/` folder, followed by the language selected, the name of the voice sample, and the text. Example of audio file from the screenshot above : `ComfyUI/Bjornulf_TTS/Chinese/default.wav/你吃了吗.wav` You can notice that you don't NEED to select a chinese voice to speak chinese. Yes it will work, you can record yourself and make yourself speak whatever language you want. Also, when you select a voice with this format `fr/fake_Bjornulf.wav`, it will create an extra folder `fr` of course. : `ComfyUI/Bjornulf_TTS/English/fr/fake_Bjornulf.wav/hello_im_me.wav`. Easy to see that you are using a french voice sample for an english recording. `control_after_generate` as usual, it is used to force the node to rerun for every workflow run. (Even if there is no modification of the node or its inputs.) `overwrite` is used to overwrite the audio file if it already exists. (For example if you don't like the generation, just set overwrite to True and run the workflow again, until you have a good result. After you can set it to back to False. (Paraphrasing : without overwrite set to True, It won't generate the audio file again if it already exists in the `Bjornulf_TTS` folder.) `autoplay` is used to play the audio file inside the node when it is executed. (Manual replay or save is done in the `preview audio` node.) So... note that if you know you have an audio file ready to play, you can still use my node but you do NOT need my TTS server to be running. My node will just play the audio file if it can find it, won't try to connect th backend TTS server. Let's say you already use this node to create an audio file saying `workflow is done` with the Attenborough voice : ![TTS](screenshots/tts_end.png) As long as you keep exactly the same settings, it will not use my server to play the audio file! You can safely turn the TTS server off, so it won't use your precious VRAM Duh. (TTS server should be using ~3GB of VRAM.) Also `connect_to_workflow` is optional, it means that you can make a workflow with ONLY my TTS node to pre-generate the audio files with the sentences you want to use later, example : ![TTS](screenshots/tts_preload.png) If you want to run my TTS nodes along side image generation, i recommend you to use my PAUSE node so you can manually stop the TTS server after my TTS node. When the VRAM is freed, you can the click on the RESUME button to continue the workflow. If you can afford to run both at the same time, good for you, but Locally I can't run my TTS server and FLUX at the same time, so I use this trick. : ![TTS](screenshots/tts_preload_2.png) ### 32 - πŸ§‘πŸ“ Character Description Generator **Description:** Generate a character description based on a json file in the folder `characters` : `ComfyUI/custom_nodes/Bjornulf_custom_nodes/characters` Make your own json file with your own characters, and use this node to generate a description. ![characters](screenshots/characters.png) ![characters](screenshots/characters2.png) ❗ For now it's very basic node, a lot of things are going to be added and changed !!! Some details are unusable for some checkpoints, very much a work in progress, the json structure isn't set in stone either. Some characters are included. ### 33 - β™» Loop (All Lines from input πŸ”— combine by lines) **Description:** Sometimes you want to loop over several inputs but you also want to separate different lines of your output. So with this node, you can have the number of inputs and outputs you want. See example for usage. ![loop combined](screenshots/loop_combined.png) ### 34 - 🧹 Free VRAM hack **Description:** So this is my attempt at freeing up VRAM after usage, I will try to improve that. ![free vram](screenshots/free_vram_hack1.png) ![free vram](screenshots/free_vram_hack2.png) For me, on launch ComfyUI is using 180MB of VRAM, after my clean up VRAM node it can go back down to 376MB. I don't think there is a clean way to do that, so I'm using a hacky way. So, not perfect but better than being stuck at 6GB of VRAM used if I know I won't be using it again... Just connect this node with your workflow, it takes anything as input and return it as output. You can therefore put it anywhere you want. ❗ Comfyui is using cache to run faster (like not reloading checkpoints), so only use this free VRAM node when you need it. ❗ For this node to work properly, you need to enable the dev/api mode in ComfyUI. (You can do that in the settings) It is also running an "empty/dummy" workflow to free up the VRAM, so it might take a few seconds to take effect after the end of the workflow. ### 35 - ⏸️ Paused. Resume or Stop ? **Description:** Automatically pause the workflow, and rings a bell when it does. (play the audio `bell.m4a` file provided) ![pause resume stop](screenshots/pause1.png) ![pause resume stop](screenshots/pause2.png) ![pause resume stop](screenshots/pause3.png) You can then manually resume or stop the workflow by clicking on the node's buttons. I do that let's say for example if I have a very long upscaling process, I can check if the input is good before continuing. Sometimes I might stop the workflow and restart it with another seed. You can connect any type of node to the pause node, above is an example with text, but you can send an IMAGE or whatever else, in the node `input = output`. (Of course you need to send the output to something that has the correct format...) ### 36 - βΈοΈπŸ” Paused. Select input, Pick one **Description:** Automatically pause the workflow, and rings a bell when it does. (play the audio `bell.m4a` file provided) ![pick input](screenshots/pick.png) You can then manually select the input you want to use, and resume the workflow with it. You can connect this node to anything you want, above is an example with IMAGE. But you can pick whatever you want, in the node `input = output`. ### 37 - πŸŽ²πŸ–Ό Random Image **Description:** Just take a random image from a list of images. ![random image](screenshots/random_image.png) ### 38 - β™»πŸ–Ό Loop (Images) **Description:** Loop over a list of images. ![loop images](screenshots/loop_images.png) Usage example : You have a list of images, and you want to apply the same process to all of them. Above is an example of the loop images node sending them to an Ipadapter workflow. (Same seed of course.) ### 39 - β™» Loop (βœ’πŸ—”πŸ…°οΈ Advanced Write Text) **Description:** If you need a quick loop but you don't want something too complex with a loop node, you can use this combined write text + loop. ![loop write text](screenshots/loop_write_text.png) It will take the same special syntax as the Advanced write text node `{blue|red}`, but it will loop over ALL the possibilities instead of taking one at random. 0.40 : You can also use variables `` in the loop. ### 40 - 🎲 Random (Model+Clip+Vae) - aka Checkpoint / Model **Description:** Just simply take a trio at random from a load checkpoint node. ![random checkpoint](screenshots/random_checkpoint.png) Notice that it is using the core Load checkpoint node. It means that all checkpoint will be preloaded in memory. Details : - It will take more VRAM, but it will be faster to switch between checkpoints. - It can't give you the currently loaded checkpoint name's. Check node number 41 before deciding which one to use. ### 41 - 🎲 Random Load checkpoint (Model Selector) **Description:** This is another way to select a load checkpoint node randomly. ![pick input](screenshots/random_load_checkpoint.png) It will not preload all the checkpoints in memory, so it will be slower to switch between checkpoints. But you can use more outputs to decide where to store your results. (`model_folder` is returning the last folder name of the checkpoint.) I always store my checkpoints in a folder with the type of the model like `SD1.5`, `SDXL`, etc... So it's a good way for me to recover that information quickly. Details : - Note that compared to node 40, you can't have separate configuration depending of the selected checkpoint. (For example `CLIP Set Last Layer` node set at -2 for a specific model, or a separate vae or clip.) Aka : All models are going to share the exact same workflow. Check node number 40 before deciding which one to use. Node 53 is the loop version of this node. NOTE : If you want to load a single checkpoint but want to extract its folder name (To use the checkpoint name as a folder name for example, or with if/else node), you can use my node 41 with only one checkpoint. (It will take one at random, so... always the same one.) ### 42 - β™» Loop (Model+Clip+Vae) - aka Checkpoint / Model ![pick input](screenshots/loop_checkpoint.png) **Description:** Loop over all the trios from several checkpoint node. ### 43 - πŸ“₯πŸ–ΌπŸ“‚ Load Images from output folder **Description:** Quickly select all images from a folder inside the output folder. (Not recursively.) ![pick input](screenshots/load_images_folder.png) So... As you can see from the screenshot the images are split based on their resolution. It's also not possible to edit dynamically the number of outputs, so I just picked a number : 4. The node will separate the images based on their resolution, so with this node you can have 4 different resolutions per folder. (If you have more than that, maybe you should have another folder...) To avoid error or crash if you have less than 4 resolutions in a folder, the node will just output white tensors. (white square image.) So this node is a little hacky for now, but i can select my different characters in less than a second. If you want to know how i personnaly save my images for a specific character, here is part of my workflow (Notice that i personnaly use / for folders because I'm on linux) : ![pick input](screenshots/character_save.png) In this example I put "character/" as a string and then combine with "nothing". But it's the same if you do "character" and then combine with "/". (I just like having a / at the end of my folder's name...) If you are satisfied with this logic, you can then select all these nodes, right click and `Convert to Group Node`, you can then have your own customized "save character node" : ![pick input](screenshots/bjornulf_save_character_group.png) Here is another example of the same thing but excluding the save folder node : ![pick input](screenshots/bjornulf_save_character_group2.png) ⚠️ If you really want to regroup all the images in one flow, you can use my node 47 `Combine images` to put them all together. ### 44 - πŸ–ΌπŸ‘ˆ Select an Image, Pick **Description:** Select an image from a list of images. ![pick input](screenshots/select_image.png) Useful in combination with my Load images from folder and preview image nodes. You can also of course make a group node, like this one, which is the same as the screenshot above : ![pick input](screenshots/select_image_group.png) ### 45 - πŸ”€ If-Else (input / compare_with) **Description:** Complex logic node if/else system. ![if else](screenshots/if_0.png) If the `input` given is equal to the `compare_with` given in the widget, it will forward `send_if_true`, otherwise it will forward `send_if_false`. (If no `send_if_false` it will return `None`.) You can forward anything, below is an example of forwarding a different size of latent space depending if it's SDXL or not. ![if else](screenshots/if_0_1.png) Here is an example of the node with all outputs displayed with Show text nodes : ![if else](screenshots/if_1.png) `send_if_false` is optional, if not connected, it will be replaced by `None`. ![if else](screenshots/if_2.png) If-Else are chainables, just connect `output` to `send_if_false`. ⚠️ Always simply test `input` with `compare_with`, and connect the desired value to `send_if_true`. ⚠️ Here a simple example with 2 If-Else nodes (choose between 3 different resolutions). ❗ Notice that the same write text node is connected to both If-Else nodes input : ![if else](screenshots/if_3.png) Let's take a similar example but let's use my Write loop text node to display all 3 types once : ![if else](screenshots/if_4.png) If you understood the previous examples, here is a complete example that will create 3 images, landscape, portrait and square : ![if else](screenshots/if_5.png) Workflow is hidden for simplicity, but is very basic, just connect latent to Ksampler, nothing special.) You can also connect the same advanced loop write text node with my save folder node to save the images (landscape/portrait/square) in separate folders, but you do you... ### 46 - πŸ–ΌπŸ” Image Details **Description:** Display the details of an image. (width, height, has_transparency, orientation, type) `RGBA` is considered as having transparency, `RGB` is not. `orientation` can be `landscape`, `portrait` or `square`. ![image details](screenshots/image_details_1.png) ### 47 - πŸ–ΌπŸ”— Combine Images **Description:** Combine multiple images (A single image or a list of images.) If you want to merge several images into a single image, check node 60 or 61. There are two types of logic to "combine images". With "all_in_one" enabled, it will combine all the images into one tensor. Otherwise it will send the images one by one. (check examples below) : This is an example of the "all_in_one" option disabled (Note that there are 2 images, these are NOT side by side, they are combined in a list.) : ![combine images](screenshots/combine_images_1.png) But for example, if you want to use my node `select an image, pick`, you need to enable `all_in_one` and the images must all have the same resolution. ![combine images](screenshots/combine_images_2.png) You can notice that there is no visible difference when you use `all_in_one` with `preview image` node. (this is why I added the `show text` node, note that show text will make it blue, because it's an image/tensor.) When you use `combine image` node, you can actually also send many images at once, it will combine them all. Here is an example with `Load images from folder` node, `Image details` node and `Combine images` node. (Of course it can't have `all_in_one` set to True in this situation because the images have different resolutions) : ![combine images](screenshots/combine_images_3.png) Here another simple example taking a few selected images from a folder and combining them (For later processing for example) : ![combine images](screenshots/combine_images_4.png) ### 48 - πŸ”€πŸŽ² Text scrambler (πŸ§‘ Character) **Description:** Take text as input and scramble (randomize) the text by using the file `scrambler/character_scrambler.json` in the comfyui custom nodes folder. ![scrambler character](screenshots/scrambler_character.png) ### 49 - πŸ“ΉπŸ‘ Video Preview **Description:** This node takes a video path as input and displays the video. ![video preview](screenshots/video_preview.png) ### 50 - πŸ–ΌβžœπŸ“Ή Images to Video path (tmp video) **Description:** This node will take a list of images and convert them to a temporary video file. ❗ Update 0.50 : You can now send audio to the video. (audio_path OR audio TYPE) ![image to video path](screenshots/image_to_video_path.png) ### 51 - πŸ“ΉβžœπŸ–Ό Video Path to Images **Description:** This node will take a video path as input and convert it to a list of images. ![video path to image](screenshots/video_path_to_image.png) In the above example, I also take half of the frames by setting `frame_interval` to 2. Note that i had 16 frames, on the top right preview you can see 8 images. ### 52 - πŸ”ŠπŸ“Ή Audio Video Sync **Description:** This node is an overengineered node that will try to synchronize the duration of an audio file with a video file. ❗ Video ideally needs to be a loop, check my ping pong video node if needed. The main goal of this synchronization is to have a clean transition between the end and the beginning of the video. (same frame) You can then chain up several video and they will transition smoothly. Some details, this node will : - If video slightly too long : add silence to the audio file. - If video way too long : will slow down the video up to 0.50x the speed + add silence to the audio. (now editable) - If audio slightly too long : will speed up video up to 1.5x the speed. (now editable) - If video way too long : will speed up video up to 1.5x the speed + add silence to the audio. It is good like for example with MuseTalk Here is an example of the `Audio Video Sync` node, notice that it is also convenient to recover the frames per second of the video, and send that to other nodes. (Spaghettis..., deal with it. 😎 If you don't understand it, you can test it.) : ![audio sync video](screenshots/audio_sync_video.png) ❗ Update 0.50 : audio_duration is now optional, if not connected it will take it from the audio. ❗ Update 0.50 : You can now send the video with a list of images OR a video_path, same for audio : AUDIO or audio_path. New v0.50 layout, same logic : ![audio sync video](screenshots/audio_sync_video_new.png) ### 53 - β™» Loop Load checkpoint (Model Selector) **Description:** This is the loop version of node 41. (check there for similar details) It will loop over all the selected checkpoints. ❗ The big difference with 41 is that checkpoints are preloaded in memory. You can run them all faster all at once. It is a good way to test multiple checkpoints quickly. ![loop model selector](screenshots/loop_model_selector.png) ### 54 - β™» Loop Lora Selector **Description:** Loop over all the selected Loras. ![loop lora selector](screenshots/loop_lora_selector.png) Above is an example with Pony and several styles of Lora. Below is another example, here with flux, to test if your Lora training was undertrained, overtrained or just right : ![loop lora selector](screenshots/loop_lora_selector_flux.png) ### 55 - 🎲 Random Lora Selector **Description:** Just take a single Lora at random from a list of Loras. ![random lora selector](screenshots/random_lora_selector.png) ### 56 - β™»πŸ“‘πŸ“ Loop Sequential (Integer) **Description:** This loop works like a normal loop, BUT it is sequential : It will run only once for each workflow run !!! The first time it will output the first integer, the second time the second integer, etc... When the last is reached, the node will STOP the workflow, preventing anything else to run after it. Under the hood it is using a single file `counter_integer.txt` in the `ComfyUI/Bjornulf` folder. ❗ Do not use more than one node like this one in a workflow, because they will share the same `counter_integer.txt` file. (unexpected behaviour.) Update 0.57: Now also contains the next counter in the reset button. ![loop sequential integer](screenshots/loop_sequential_integer_1.png) ![loop sequential integer](screenshots/loop_sequential_integer_2.png) ![loop sequential integer](screenshots/loop_sequential_integer_3.png) ![loop sequential integer](screenshots/loop_sequential_integer_4.png) ### 57 - β™»πŸ“‘ Loop Sequential (input Lines) **Description:** This loop works like a normal loop, BUT it is sequential : It will run only once for each workflow run !!! The first time it will output the first line, the second time the second line, etc... You also have control of the line with +1 / -1 buttons. When the last is reached, the node will STOP the workflow, preventing anything else to run after it. Under the hood it is using the file `counter_lines.txt` in the `ComfyUI/Bjornulf` folder. Here is an example of usage with my TTS node : when I have a list of sentences to process, if i don't like a version, I can just click on the -1 button, tick "overwrite" on TTS node and it will generate the same sentence again, repeat until good. ❗ Do not use more than one node like this one in a workflow, because they will share the same `counter_lines.txt` file. (unexpected behaviour.) ![loop sequential line](screenshots/loop_sequential_lines.png) Update 0.57: Now also contains the next counter in the reset button. If you want to be able to predict the next line, you can use node 68, to Add line numbers. ### 58 - πŸ“ΉπŸ”— Concat Videos **Description:** Take two videos and concatenate them. (One after the other in the same video.) Convert a video, can use FFMPEG_CONFIG_JSON. (From node 76 / 77) ![concat video](screenshots/concat_video.png) ### 59 - πŸ“ΉπŸ”Š Combine Video + Audio **Description:** Simply combine video and audio together. Video : Use list of images or video path. Audio : Use audio path or audio type. ![combine video audio](screenshots/combine_video_audio.png) ### 60 - πŸ–ΌπŸ–Ό Merge Images/Videos πŸ“ΉπŸ“Ή (Horizontally) **Description:** Merge images or videos horizontally. ![merge images](screenshots/merge_images_h.png) Here is one possible example for videos with node 60 and 61 : ![merge videos](screenshots/merge_videos.png) ### 61 - πŸ–ΌπŸ–Ό Merge Images/Videos πŸ“ΉπŸ“Ή (Vertically) **Description:** Merge images or videos vertically. ![merge images](screenshots/merge_images_v.png) Here is one possible example for videos with node 60 and 61 : ![merge videos](screenshots/merge_videos.png) ### 62 - πŸ¦™πŸ‘ Ollama Vision **Description:** Take an image as input and will describe the image. Uses `moondream` by default, but can select anything with node 63. ![ollama vision](screenshots/ollama_vision.png) ### 63 - πŸ¦™ Ollama Configuration βš™ **Description:** Use custom configurations for Ollama Talk and Vision. You can change the ollama Url and the model used. Some vision models can also do text to a certain extent. Example of a `Ollama Vision Node` and `Ollama Talk Node` using the same `Ollama Configuration Node` : ![ollama config](screenshots/ollama_config.png) ### 64 - πŸ¦™ Ollama Job Selector πŸ’Ό **Description:** Select a personnality for your Ollama Talk Node, set it to `None` for just chat. If you want to write your own, just set it to `None` and write your prompt as prefix. ![ollama job](screenshots/ollama_job.png) ### 65 - πŸ¦™ Ollama Persona Selector πŸ§‘ **Description:** Select a personnality for your Ollama Talk Node. If you want to write your own, just set it to `None` and write your prompt as prefix. Below, an example of a crazy scientist explaining gravity. (Notice that the LLM was smart enough to understand the typo) : ![ollama persona](screenshots/ollama_persona.png) ### 66 - πŸ”ŠβžœπŸ“ STT - Speech to Text **Description:** Use `faster-whisper` to transform an AUDIO type or audio_path into text. (Autodetect language) ![stt](screenshots/stt_1.png) ![stt](screenshots/stt_2.png) ### 67 - πŸ“βžœβœ¨ Text to Anything **Description:** Sometimes you want to force a node to accept a STRING. You can't do that for example if the node is taking a LIST as input. This node can be used in the middle to force a STRING to be used anyway. Below is an example of that with my TTS node. ![text to anything](screenshots/text_to_anything.png) ### 68 - βœ¨βžœπŸ“ Anything to Text **Description:** Sometimes you want to force something to be a STRING. Most outputs are indeed text, even though they might be unusable. This node ignore this fact and simply convert the input to a simple STRING. ### 69 - πŸ”’ Add line numbers **Description:** This node will just add line numbers to text. Useful when you want to use node 57 that will loop over input lines. (You can read/predict the next line.) ![add line numbers](screenshots/add_line_numbers.png) ### 70 - πŸ“ Resize Image Percentage **Description:** Resize an image by percentage. ![resize percentage](screenshots/resize_percentage.png) ### 71 - πŸ‘ Show (Int) **Description:** Basic node, show an INT. (You can simply drag any INT node and it will be recommended.) ![show int](screenshots/show_int.png) ### 72 - πŸ‘ Show (Float) **Description:** Basic node, show a FLOAT. (You can simply drag any FLOAT node and it will be recommended.) ![show float](screenshots/show_float.png) ### 73 - πŸ‘ Show (String/Text) **Description:** Basic node, show a STRING. (You can simply drag any STRING node and it will be recommended.) ![show string](screenshots/show_string_1.png) ![show string](screenshots/show_string_2.png) ### 74 - πŸ‘ Show (JSON) **Description:** This node will take a STRING and format it as a readable JSON. (and pink) ![show json](screenshots/show_json.png) ![show json](screenshots/show_json2.png) ### 75 - πŸ“βžœπŸ“ Replace text **Description:** Replace text with another text, allow regex and more options, check examples below : ![text replace](screenshots/text_replace_1.png) ![text replace](screenshots/text_replace_2.png) ![text replace](screenshots/text_replace_3.png) 0.70 ： Text replace now have multiline option for regex. ### 76 - βš™πŸ“Ή FFmpeg Configuration πŸ“Ήβš™ **Description:** Create a FFMPEG_CONFIG_JSON, it will contains a JSON that can be used by other nodes : - Convert video - Concat videos - Concat video from list ![text replace](screenshots/ffmpeg_conf.png) ### 77 - πŸ“ΉπŸ” Video details βš™ **Description:** Extract details from a video_path. You can use the all-in-one FFMPEG_CONFIG_JSON with other nodes or just use the other variables as your want. ![video details](screenshots/video_details.png) ### 78 - πŸ“ΉβžœπŸ“Ή Convert Video **Description:** Convert a video, can use FFMPEG_CONFIG_JSON. ![convert video](screenshots/convert_video.png) #### 79 - πŸ“ΉπŸ”— Concat Videos from list **Description:** Take a list of videos (one per line) and concatenate them. (One after the other in the same video.) Can use FFMPEG_CONFIG_JSON. (From node 76 / 77) ![concat video list](screenshots/concat_video_list.png) #### 80 - 🩷 Empty Latent Selector **Description:** Tired of setting up latent space manually ? Select one from my custom list of formats. Just connect that to your KSampler. ![empty_latent](screenshots/empty_latent.png) #### 81 - πŸ”₯πŸ“ Text Generator πŸ“πŸ”₯ **Description:** Main node to generate content, doesn't really do much by itself, just `camera angle` and `multicharacter action`. (For example : `... eat picnic, view from above.`) BUT, you can connect others `Text Generator Nodes` to it. ⚠️ Warning for "Text Generator" : This node is JUST writing text, text is then interpreted by a checkpoint (SD1.5, SDXL, Flux...) to generate an image. Some models are very bad at doing some things, so DON'T EXPECT for everything you do to work properly all the time with every checkpoints or loras. (This node was made with FLUX in mind.) Below is a Tutorial on how to use all my `Text Generator nodes`. I did that small tutorial in 8 steps: Step 1 : You use the main Text Generator node, it will write general details about the image (here `camera_angle` and `shot_type`) - For now I just combine the text to a simple "write text" that will send `swamp monster` : ![textgen](screenshots/textgen.png) Step 2 : Add a specific style to your image : ![textgen_style](screenshots/textgen_style.png) Step 3 : Add scene/background to your image : ![textgen_scene](screenshots/textgen_scene.png) Step 4 : Add a character to the scene using a character node, instead of the Write text Node. I will remove the "swamp monster" from the "write text node" and use my Character Node instead, I will use it to create an agressive dragon with lighting powers : ![textgen_char](screenshots/textgen_char.png) Step 5 : Character nodes (Male/Female and creatures) can contain more than one character. (But they will share the same characteristics) Below I removed the dragon and I created 2 "Character male" fighting by using the `multi_char_action` from the main node. (You can set it to CUSTOM and write your own action too.) ![textgen_2chars](screenshots/textgen_2chars.png) Step 5 : Let's try to add a location for the character, I want to put it on the left of the image. Here is a failure with the SDXL model I have been using all along : ![textgen_charposition_FAIL_sdxl](screenshots/textgen_charposition_FAIL_sdxl.png) Step 6 : Switch to FLUX to test the `location_on_image` feature (which is working) : ![textgen_location_on_image_flux](screenshots/textgen_location_on_image_flux.png) Step 7 : Switch to API black Forest Lab with FLUX Ultra, using my API custom node 109. If you want several characters with different characteristics (like `location_on_image` or whatever), you can chain several Character Nodes together by connecting them to each other. You can see below that I asked for 2 tiny dragons on the left and a zombie on the right. ![textgen_Complex_ULTRA](screenshots/textgen_Complex_ULTRA.png) Step 8 : And to end this tutorial, I will disable the Zombie, I will add an outfit (here a `floral armor`), I will also add a `pose` node for the character and also connect this pose node to an `object` node. (They will together make the character `hold a book` and put his `hand on chin`) ![textgen_final](screenshots/textgen_final.png) #### 82 - πŸ‘©β€πŸ¦°πŸ“ Text Generator (Character Female) **Description:** Generate text related to female characters. Need to be connected to "Text Generator" main node. ⚠️ For "Text Generator" tutorial see node 81. #### 83 - πŸ‘¨β€πŸ¦°πŸ“ Text Generator (Character Male) **Description:** Generate text related to male characters. ⚠️ For "Text Generator" tutorial see node 81. #### 84 - πŸ‘ΎπŸ“ Text Generator (Character Creature) **Description:** Generate text related to creatures. (characters) ⚠️ For "Text Generator" tutorial see node 81. #### 85 - πŸ’ƒπŸ•ΊπŸ“ Text Generator (Character Pose) **Description:** Generate text related to the pose of characters. ⚠️ For "Text Generator" tutorial see node 81. #### 86 - πŸ”§πŸ‘¨β€πŸ”§πŸ“ Text Generator (Object for Character) **Description:** Generate text related to an object connected to a pose, that is connected to a character. ⚠️ For "Text Generator" tutorial see node 81. #### 87 - πŸŒ„πŸ“ Text Generator (Scene) **Description:** Generate text related to a specific scene, connects directly to the main text generator. ⚠️ For "Text Generator" tutorial see node 81. #### 88 - πŸŽ¨πŸ“ Text Generator (Style) **Description:** Generate text related to a specific style, connects directly to the main text generator. ⚠️ For "Text Generator" tutorial see node 81. #### 89 - πŸ‘— Text Generator (Outfit Female) **Description:** Generate text related to a specific female outfit. ⚠️ For "Text Generator" tutorial see node 81. #### 90 - πŸ‘š Text Generator (Outfit Male) **Description:** Generate text related to a specific male outfit. ⚠️ For "Text Generator" tutorial see node 81. #### 91 - β™»πŸ”₯πŸ“ List Looper (Text Generator) **Description:** Loop made to loop over elements for the main node text generator. All the `List Looper` nodes have the same logic, you should be able to use them all the same way. Here is an example with node 92 (list looper scenes), looping over all the different `weather_condition` : ![listlooper_USE](screenshots/listlooper_USE.png) ⚠️ Note, if you want to Loop over the elements `One by One`, Not all-in one, DO NOT use this `list looper nodes` !! You can just convert the element you want as input and double click to create a new node that you can set to "increment". Example, here you can see that the value was "incremented", aka changed to the next from the list, the next run will then have the next value from the list (and so on) : ![listlooper_notUSE](screenshots/listlooper_notUSE.png) #### 92 - β™»πŸŒ„πŸ“ List Looper (Text Generator Scenes) **Description:** Loop made to loop over elements for the node scenes. ⚠️ For "List Looper" tutorial see node 91. #### 93 - β™»πŸŽ¨πŸ“ List Looper (Text Generator Styles) **Description:** Loop made to loop over elements for the node style. ⚠️ For "List Looper" tutorial see node 91. #### 94 - β™»πŸ’ƒπŸ•ΊπŸ“ List Looper (Text Generator Poses) **Description:** Loop made to loop over elements for the node poses. ⚠️ For "List Looper" tutorial see node 91. #### 95 - β™»πŸ‘¨β€πŸ¦°πŸ‘©β€πŸ¦°πŸ‘Ύ List Looper (Text Generator Characters) **Description:** Loop made to loop over elements for the node charceter (male/female/creature). ⚠️ For "List Looper" tutorial see node 91. #### 96 - β™»πŸ‘š List Looper (Text Generator Outfits Male) **Description:** Loop made to loop over elements for the node for male outfits. ⚠️ For "List Looper" tutorial see node 91. #### 97 - β™»πŸ‘— List Looper (Text Generator Outfits Female) **Description:** Loop made to loop over elements for the node for female outfits. ⚠️ For "List Looper" tutorial see node 91. #### 98 - πŸ“₯ Load checkpoint SD1.5 (+Download from CivitAi) **Description:** This is the same as a basic "Load checkpoint" node, but the list is from civitai (not your local folder).

(No external backend to run.) ![tts kokoro](screenshots/kokoro_tts.png) #### 121 - πŸ’Ύ Huggingface Downloader **Description:** This node allows you to download models/vae/unet etc... directly from huggingface with your access token. ![huggingface dl](screenshots/huggingface_dl.png) #### 122 - πŸ‘‘ Combine Loras, Lora stack **Description:** If you want to have multiple loras in a single node, well this is it. ![Lora stack](screenshots/lora_stacks.png) #### 123 - πŸ’ΎπŸ…°οΈ Save Global Variables **Description:** So if you know how to use variables with my nodes, this node gives you the opportunity to create global variables. This node is very simple, it will just append (or overwrite) the file : `Bjornulf/GlobalVariables.txt` (You can edit that manually if you want.) ![Global Save](screenshots/global_save.png) #### 124 - πŸ“₯πŸ…°οΈ Load Global Variables **Description:** This node will load the global variables as text from the file `Bjornulf/GlobalVariables.txt`. Here is an example of usage save/load : ![Global images](screenshots/global_load.png) #### 125 - πŸ“πŸ‘ˆ Model-Clip-Vae selector (🎲 or β™» or β™»πŸ“‘) **Description:** If you want to use and manage multiple models/clip/vae : this is the universal node for it. You can run them in a LOOP, one at RANDOM, a LOOP SEQUENTIAL (one at a time for each workflow run) and even SELECT a specific one. ![model clip vae selector](screenshots/model_clip_vae_selector.png) #### 126 - πŸ“’ Note **Description:** Sometimes I want to add a NOTE but I want this note to be connected to a specific spaghetti. So you can use this to write details about a specific connection, it will move with it. You can do whatever you want of course, below is an example about HunYuan video generation. (You can quickly switch connection to the rest of your workflow, depending on what you want to run.) ![note](screenshots/note.png) #### 127 - πŸ–ΌπŸ“’ Image Note **Description:** You can use this node to have it show a previously generated image and some custom text. (Use image_path or IMAGE type.) ![Image note](screenshots/image_note.png) You can use the text to display the prompt used to generate the image for example. It's behavior is like a "Preview image" node. (See node 130 if you want a behavior similar to "Load image") Sometimes I want to display an image to explain what something specific is doing visually. (For example a stack of loras will have a specific style.) Here is a complex example on how i use that, for a list of loras stacks. (I then "select" a style by using node `125 - Model-Clip-Vae selector`) ![Image note](screenshots/image_notes.png) #### 128 - πŸ–ΌπŸ‘ Preview (first) image **Description:** This node can display a preview of an image... - But also can take a list of images and preview only the first image. (Useful for video, it will take the first image.) - But can also take as input the full path of an image. - BUT it can also take a video path as input and extract the first frame of it. Very useful for testing when working with videos. Below is a visual example of what I just said : ![First image preview](screenshots/first_image_preview.png) #### 129 - πŸ“ŒπŸ…°οΈ Set Variable from Text **Description:** This node will just quickly transform a text in another text which can be quickly used for all my variables nodes. Here is an example below with "Advanced write text", but you can use with all of them, global variables, etc... ![text_to_variable](screenshots/text_to_variable.png) #### 130 - πŸ“₯πŸ–ΌπŸ“’ Image Note (Load image) **Description:** This node is quite similar to the node 127. But this one uses LoadImage instead of a preview system. So if you want to have a "preview" before you launch workflow one time, you can use this one. It's behaviour is like a "Load image" node. ![Image note Load](screenshots/note_load_image.png) #### 131 - βœ’πŸ‘‰ Write Pick Me Chain **Description:** So this is a new "write text" node. But with a twist. You can connect them to each other and when clicking on the PICK ME button, it will disable all other write text node of the chain and activate only the one you click on. (It will turn green.) So with this node, you can switch from one prompt to another by the click of a button !! Not limited to one line, you can use list, variables, etc... but below is a simple example : ![write pick me chain](screenshots/write_pick_me_chain.png) #### 132 - πŸ“πŸ”ͺ Text split in 10 **Description:** Same as node 113, but split in 10 parts. One day I had 6, and got stuck with the split in 5 node, so i guess it can be useful sometimes, let's make one with 10... ![text split 10](screenshots/text_split_10.png) #### 133 - πŸ–ΌπŸ‘ Preview 1-4 images (compare) **Description:** Cool node that you can use to compare several images. The middle is a cursor that you can move wherever you want by just clicking on the image. Below is an example, you can see that at this size/resolution, 25% is almost as good as the initial image. ![four previews](screenshots/four_preview.png) Here is a zoom on the same image : ![four previews](screenshots/four_preview_zoom.png) #### 134 - πŸ”Šβ–Ά Play Audio **Description:** This node will just play a bell. For example, if you have a workflow that takes a while and you want to be alerted every time it's over. ![play_audio_1](screenshots/play_audio_1.png) You can connect to it a custom path of an audio file : ![play_audio_2](screenshots/play_audio_2.png) Or send it an AUDIO type format : ![play_audio_3](screenshots/play_audio_3.png) #### 135 - πŸ”›βœ¨ Anything Switch On/Off **Description:** Basic switch that will not send anything if toggled off. below is an example with the compatible "combine image node", here you can see that the top image was ignored. ![switch_anything](screenshots/switch_anything.png) #### 136 - πŸ”›πŸ“ Text Switch On/Off **Description:** Tired of disconnecting nodes you don't want for a moment ? Maybe you are working on this input, but your workflow isn't ready for it yet ? Well now you can quickly enable / disable it. (If disabled you will see it in red.) ![switch_text](screenshots/switch_text.png) If connected with my combine text node, you can use a special option `ONLY_ME_combine_text` that will tell combine text to write ONLY the selected node. It will ignore all the otehrs. (Here will appear in blue.) : ![switch_text_onlyme](screenshots/switch_text_onlyme.png) #### 137 - 🌎🎲 Global Seed Manager **Description:** Seed manager. It is : - Generating a random seed every run. - Return the current seed as a STRING that you can use in other nodes with STRING format. - Return the value of the previously used seed. - Will save all the seeds used inside a file. (that you can reset with a button.) If you want to select a seed from this list, use node 138. ![global_seed_manager](screenshots/global_seed_manager.png) #### 138 - πŸ“‘πŸ‘ˆ Select from List **Description:** Select quickly an element from a LIST. (a STRING with elements separated by ; by default) Example of LIST : a;b;c;d Below is an example for quickly selecting the third seed used by Global Seed Manager : ![select_from_list](screenshots/select_from_list.png) #### 139 - 🎲 Random Integer **Description:** Simply return an INT in between the 2 values provided. ![random_int](screenshots/random_int.png) #### 140 - 🎲 Random Float **Description:** Simply return a FLOAT in between the 2 values provided. ![random_float](screenshots/random_float.png) #### 141 - πŸŒŽβœ’πŸ‘‰ Global Write Pick Me **Description:** Do you enjoy Pick Me chain nodes ? This one is using IDENTIFIERS (global_pickme_id) instead of connections. Just pick up a name as global_pickme_id and if the nodes have the same global_pickme_id they will automatically connect to each other. Below is an example of write + load : ![global_write_pickme_load](screenshots/global_write_pickme_load.png) #### 142 - 🌎πŸ“₯ Load Global Pick Me **Description:** The node used to recover the values from PICK ME global write nodes. It will return the value from the currently selecte global_pickme_id. This node also automatically return a random value from the list with the global_pickme_id. Below is an example of write + load : ![global_write_pickme_load](screenshots/global_write_pickme_load.png)
