Hi PaQ,

Well, looks like mach banding artifacts.

Is there any setting in materials to do full Phong shading?

Maybe it's not doing very careful interpolation of the normal or something like that.

As you can see in the Cinema4D renders, if the vertex normals are treated carefully by the renderer so that each individual pixel ends up getting shaded by a good normal, it makes for nice results even with a pretty rough mesh.

Maybe it is not as common to do that as I had thought though.
