Easy Material Mask provides a straightforward method for generating flat render colors for individual materials while preserving alpha channels. The tool is designed to assist with post-processing and compositing workflows by creating distinct colored masks for different parts of a scene.

The package includes a Python add-on that assigns random material IDs and a ready-to-use compositor node group that can be saved to the asset library. Users can generate the IDs via the tool tab and then process them in the compositor by connecting the IndexMA pass to the provided node.
