In the context of the Corona Layered Material, why does it make sense for Layer 1 to inherit displacement information from the base layer, but not bump information?
It would be great if there were a way to control the influence of bump information from an underlying layer (e.g. base material) on a subsequent layer (e.g. Layer 1).
The CoronaPhysicalMtl base bump and clearcoat bump provide a (sort of) paradigm to think about how this functionality might work.
