The Color ID Composer is an add-on that automates the generation of solid color IDs for external masking and compositing workflows in applications like Nuke, Photoshop, and Substance Painter. It unifies several ID generation methods into a single toolset, providing an alternative to standard cryptomattes.

The tool calculates and assigns unique colors based on specific physical scene properties. Users can drive color ID assignments using parameters such as axis direction, object distance from the camera, field of view limitations, and specific geometry selection tools. This allows for precise control over how masks are generated for VFX and rendering pipelines.
