I want to make an Ambient Occlusion render layer. When I make a render layer in Render Setup, and assign all the objects from my scene, and assign a material override to it, only about half of my objects are getting the new material. The others give errors like:
# Warning: Node 'TrashCanMeshShape.instObjGroups[0].objectGroups[0]': cannot make assignment to 'aiAmbientOcclusion3SG' shader. # # Warning: Failed to make connection for material override materialOverride1. Note that per-face assignments are not supported with material overrides. #
However, I am able to apply the same material to the object manually, making me believe this is a bug. I can do the workaround of applying the material to everything as a separate scene file, but I wanted to report the bug, or perhaps learn how I could actually fix it. I stripped my scene down to a single object that is getting errors when I try to view the render layer and attached it here. Thank you!
