at Rhino5 I run in the problem that I setup a tile texture for an Enscape rendering, but found no texture slot to control the difference of Reflectivity of gap material and glossy tile.
So finally, I think on the long run we need a texture slot for Reflectivity and Gloss finish. I hope it can be added to Rhino 6. It’s important for Enscape rendering since this tool based on the Rhino materials. It think it could be a great deal for McNeel to help to get most from Enscape, since this is an impressive RT VR tool and I think, Rhino will profit from this connection.
