Hello @keiiketani, and welcome to our community!

Thank you for creating your post. I wanted to clarify: the Mesh ID Map baker is functioning correctly; however, it calculates the ID Map for each of the individual source meshes by default. I’ve adjusted the title of your post to clarify your question for others.

Currently, it is not possible to bake the source mesh’s material colors into an ID map. However, you could bake a Vertex Color map if you want to use fixed colors for a Mesh ID map. Once the vertex colors are assigned to the source mesh, you can enable the Vertex Color baker in the Mesh Baking panel. Once the vertex color map has been baked, you can assign it to the Mesh ID map area in the Layering Project Editor.

Please feel free to let us know if you have any further questions.

Thanks!
