Hi,
I have a mesh with a Vertex Color attribute "Cd" in SOPs. When I use a ImportSOP node in Solaris and render the scene, I can see, that the Vertex Colors did come over into Solaris together with the mesh.
What I would like now, is to change reflections on the mesh, but the Principled shader overrides the Vertex Colors. When I try to set it up as Redshift Material, with either a RSuserDataColor or RSvertexAttributeLookup node to read the vertex color data and feed it into the diffuse color of the material node, these seem to come up empty and don't seem to find the Cd attribute.
Is there some kind of conversion to primvars going on behind the scenes, that renames the attribute? The data is definitely there in some form, as seen whene rendering without any material assigned, but how do I feed it into my new material?
Cheers,
Ivan
