I decided to make a quick video on using displacement mapping with Renderman PxrLMSubsurface shaders. Basically, the bump mapping for their subsurface shader is lack-luster… sort of. It definitely has its place but in general it’s more of a subtlety than anything else.
When using displacement mapping with their subsurface shader you have to apply it to the shading group itself. It doesn’t always popup in the Attributes Panel so you might have to track it down through the Hypershade window.
Here’s my monkey with a knitted body and flight suit using a displacement map on the PxrLMSubsurface shading group.
