🔗 Comfyui : Bjornulf_custom_nodes v0.23 🔗
☁ Usage in cloud :
If you want to use my nodes and comfyui in the cloud, I'm managing an optimized template on runpod : https://runpod.io/console/deploy?template=r32dtr35u1&ref=tkowk7g5
Template name : bjornulf-comfyui-allin-workspace, can be operational in ~3 minutes. (Depending on your pod)
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$/hour)
⚠️ When pod is ready, you need to open a terminal in browser (After clicking on connect from your pod) and use this to launch ComfyUI manually : cd /workspace/ComfyUI && python main.py --listen 0.0.0.0 --port 3000 (Much better to control it with a terminal, check logs, etc...)
After that you can just click on the Connect to port 3000 button.
As file manager, you can use the included JupyterLab on port 8888.
If you have any issues with it, please let me know.
For me : I have a computer with 4070 super with 12Gb and flux fp8 simple wokflow is about ~40 seconds. With a 4090 in the cloud I can run flux fp16 in ~12 seconds.
It will manage everything in Runpod network storage (/workspace/ComfyUI), so you can stop and start the cloud GPU without losing anything, change GPU or whatever.
Zone : I recommend EU-RO-1, but up to you.
Top-up your Runpod account with minimum 10$ 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, here is all you need for flux as an example :

📝 Nodes descriptions
1/2 - 👁 + ✒ Show/Write Text
Description:
Three simple nodes to write and show text.
Write node is a textarea where you can write your text.
The show text node will only display the text. (That's why I made it a different color : green, uneditable, display only.)
Write text node now allow for special syntax to accept random variants, like {hood|helmet} will randomly choose between hood or helmet.
3 - 🔗 Combine Texts
Description:
Combine multiple text inputs into a single output. (can have separation with : comma, space, new line.)
4 - 🎲 Random Text
Description:
Generate and display random text from a predefined list. Great for creating random prompts.
5 - ♻ Loop
Description:
General-purpose loop node.
6 - ♻ Loop Texts
Description:
Cycle through a list of text inputs. Great for creating dynamic text-based presentations.
7 - ♻ Loop Integer
Description:
Iterate through a range of integer values, good for steps in ksampler, etc...
❗ Don't forget that you can convert ksampler widgets to input by right-clicking the ksampler node :
8 - ♻ Loop Float
Description:
Loop through a range of floating-point numbers, good for cfg, denoise, etc...
10 - ♻ Loop All Samplers
Description:
Iterate over all available samplers to apply them sequentially. Ideal for testing.
11 - ♻ Loop All Schedulers
Description:
Iterate over all available schedulers to apply them sequentially. Ideal for testing.
12 - ♻ Loop Combos
Description:
Generate a loop from a list of my own custom combinations (scheduler+sampler), or select one combo manually.
Good for testing.
13/14 - 📏 + 🖼 Resize and Save Exact name ⚠️💣
Description:
Resize an image to exact dimensions. The other node will save the image to the exact path.
⚠️💣 Warning : The image will be overwritten if it already exists.
15 - 💾 Save Text
Description:
Save the given text input to a file. Useful for logging and storing text data.
16 - 🖼💬 Save image for Bjornulf LobeChat (❗For my custom lobe-chat❗)
Description:
❓ I made that node for my custom lobe-chat to send+receive images from Comfyui API : 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.
17 - 🖼 Save image as tmp_api.png Temporary API ⚠️💣
Description:
Save image for short-term use : ./output/tmp_api.png ⚠️💣
18 - 🖼📁 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.
19 - 🦙 Ollama
Description:
Will generate detailed text based of what you give it.
I recommend using mistral-nemo if you can run it, but it's up to you. (Might have to tweak the system prompt a bit)
⚠️ Warning : Having an ollama node that will run for each generation might be a bit heavy on your VRAM. Think about if you really need it or not.
Description:
Straight forward node to write and show text.
20 - 📹 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.
21 - 📹 Images to Video
Description:
Combine a sequence of images into a video file.
❓ 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 - 🔲 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.
23 - 🔲 Image to grayscale (black & white)
Description:
Convert an image to grayscale (black & white)
Example : I sometimes use it with Ipadapter to disable color influence.
But you can sometimes also want a black and white image...
24 - 🖼+🖼 Combine images (Background + Overlay)
Description:
Combine 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.)
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 🖼 Load Image with Transparency ▢ instead of the Load Image node.
25 - 🟩➜▢ Green Screen to Transparency
Description:
Transform greenscreen into transparency.
Need clean greenscreen ofc. (Can adjust threshold but very basic node.)
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.)
27 - ♻ Loop (All Lines from input)
Description:
Iterate over all lines from an input text. (Good for testing multiple lines of text.)
28 - 🔢 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 (♻), 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)
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)
Here is an example of the similarities that you want to avoid with FLUX with different prompt (hood/helmet) but same seed :
Here is an example of the similarities that you want to avoid with SDXL with different prompt (blue/red) but same seed :
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 :
29 - 🖼 Load Image with Transparency ▢
Description:
Load an image with transparency.
The default Load Image node will not load the transparency.
30 - 🖼✂ Cut image with a mask
Description:
Cut an image from a mask.
31 - 🔊 TTS - Text to Speech
Description:
Use my TTS server to generate speech from text.
❗ Of course you need to use my TTS server : https://github.com/justUmen/Bjornulf_XTTS
After having that 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 must be a link to the folder where you store 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 http://localhost:8020/tts_stream?language=en&speaker_wav=default&text=Hello) and voice samples are good, you can use this node to generate speech from text.
32 - 🧑📝 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.
❗ 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.
33 - ♻ Loop (All Lines from input 🔗 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.
34 - 🧹 Free VRAM hack
Description:
So this is my attempt at freeing up VRAM after usage, I will try to improve that.
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 an image as input and return the same image without any changes.
❗ 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)
35 - ⏸️ Paused. Resume or Stop ?
Description:
Automatically pause the workflow, and rings a bell when it does. (play the audio bell.m4a file provided)
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...)
