Thanks but that's not quite what I meant, try this for example: Create a poly plane, try and select the faces of one side of the plane and apply a shader, next try and select the other side and apply a different shader to it? The problem is you don't seem to be able to select the other side as the faces from the first side are considered by maya to be the same as the reverse! I think that makes some kinda sense? Any ideas?? THX, James.
