ComfyUI-CoCoTools (DEPRECATED)

⚠️ DEPRECATED: This repository is no longer maintained. Please use ComfyUI-CoCoTools_IO for the IP module and future updates.

A set of custom nodes for ComfyUI providing advanced image processing, file handling, and utility functions.

Features

  • Image processing utilities
  • EXR image input and outputs nodes
  • JSON-based scaling tools for file/path management
  • Utility nodes for image and data operations

Installation for comfyui portable (tested on 0.3.14)

from the python_embeded/ folder

python.exe -m pip install -r ./ComfyUI/custom_nodes/ComfyUI-CoCoTools/requirements.txt

Manual Installation

  1. Clone the repository into your ComfyUI custom_nodes directory
  2. Install dependencies
  3. Restart ComfyUI

To-Do

IO

  • [x] implement proper exr loading
  • [ ] implement EXR sequence loader
  • [x] implement exr saver for proper exr saving using OpenImageIO
  • [x] implement multilayer exr system ( render passes, aovs, embedded images, etc) (still testing - alpha)
  • [x] contextual menus from the file type picked on saver

Color

  • [x] split colorspace conversion into separate node
  • [x] implement minimal color management system
  • [ ] Add ACES or OCIO color config profiles into the conversion node

Processing

  • [ ] create split frequency for video node
  • [ ] create some experimental frequency tools ( motion detection from frame offset seperation)

Documentation

  • [ ] add more info on specific nodes
  • [ ] add more workflows to show how to use custom nodes
  • [] visual examples in the readme

Registration

  • [ ] submit to ComfyUI Registry
