I am trying to add specular maps to materials in rhino 6 but can't figure out how to do it or if it is even possible in the current version of enscape for rhino. I'm using the rhino renderer for materials and in custom materials there are slots for color, transparency, bump, and environment, but not specular. Do you know where I can find a slot to add a specular bitmap that works in enscape for rhino?
Lewis Williams - you can only add Specular Maps when using VRay or Brazil for Rhino, and Rhino does not have a slot for this in its native texture mapping solution, so the only solution is to control this via the Gloss and Reflection, as well as the Refl. polish settings in Rhinos native material editor.
