I’m interested in using Blender in conjunction with Renderman, so I’ve recently turned to using the Mosaic plugin. One thing I can’t figure out though, is how to preserve light/material groups in the conversion from a Blender scene to RIB files. For example, in Blender I can specify that Materials A and B are lit exclusively by lights contained in group A, while Material C is affected only by lights contained in group B.
Does anyone know how to preserve this relation in Mosaic?
