📝 Nodes descriptions
1/2 - 👁 + ✒ Show/Write Text
Description:
Two 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.)
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 API (❗For my custom lobe-chat❗)
Description:
It will save the image with the name of api_next_image.txt, which will be incremented each time you run the node.
The name will start at api_00001.png, then api_00002.png, etc...
❓ I made that for my custom lobe-chat to send+receive images from Comfyui API : lobe-chat
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, liek 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...
