https://github.com/Conor-Collins/ComfyUI-CoCoTools_IO

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

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
