ComfyUI-CoCoTools_IO
A streamlined set of custom nodes for ComfyUI focused on advanced image I/O operations, particularly for EXR file handling.
Features
- Advanced EXR image input with multilayer support
- EXR layer extraction and manipulation
- High-quality image saving with format-specific options
- Standard image format loading with bit depth awareness
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
- Clone the repository into your ComfyUI
custom_nodes
directory - Install dependencies
- Restart ComfyUI
Current Nodes
Image I/O
- Image Loader: Load standard image formats (PNG, JPG, WebP, etc.) with proper bit depth handling
- Load EXR: Comprehensive EXR file loading with support for multiple layers, channels, and cryptomatte data
- Load EXR Layer by Name: Extract specific layers from EXR files (similar to Nuke's Shuffle node)
- Cryptomatte Layer: Specialized handling for cryptomatte layers in EXR files
- Image Saver: Save images in various formats with format-specific options (bit depth, compression, etc.)
Image Processing
- Colorspace: Convert between sRGB and Linear colorspaces
- Z Normalize: Normalize depth maps and other single-channel data
To-Do
IO
- [x] Implement proper EXR loading
- [ ] Implement EXR sequence loader
- [x] Implement EXR saver using OpenImageIO
- [x] Implement multilayer EXR system (render passes, AOVs, embedded images, etc.)
- [x] Add contextual menus based on selected file type in saver
Future Enhancements
- [ ] Add ACES or OCIO color config profiles
