🎨 CryptoMatte ID Color

What it does

CryptoMatte ID Coloris a plugin that conveniently generates ID channels using CryptoMatte nodes. Many people like to use Workbench to render single color images for ID channels, but unfortunately, Workbench cannot customize each color. This plugin allows you to customize the HSV value of a specified channel and can also randomly generate the desired state multiple times. It intelligently generates and connects a corresponding number of nodes based on the total number of objects or materials in the current scene. You can preview the result through the Viewer in real time, and optionally export multilayer EXR masks for later compositing.

⚡ Key Features

• Object ID node group: generate color-coded IDs for visible renderable objects.
• Material ID node group: create material-based ID color outputs from visible scene materials.
• Real-time color editing: pick one object and adjust its ID color directly.
• Random ID colors: reshuffle existing ID colors when the scene needs clearer separation.
• Viewer-ready setup: connect generated ID output to Blender's compositor Viewer.
• Multilayer EXR export: write Object ID or Material ID layers to EXR when needed.
• Shortcut support: use quick hotkeys for Object ID, Material ID, Change ID, and Random ID.
• Chinese / English support: a smoother workflow in both language modes.
