Static lighting will not bounce on the ceiling when using a Layered Material. The Material Attributes Layers node is used which doesn't appear in 4.24.3 so this isn't a regression.
This was reported and tested in 4.25.3 (CL-13942748) and reproduced in Main 4.26 (CL-14049719)
Results: Layered materials prevent static lights from bouncing and will make some meshes appear black.
Expected: Bounced static lighting expected, and is achieved by replacing layered materials with non-layered ones.
