I have some difficulties here choosing individual tabs, in my case materials and textures, when pressing rmb and choosing e.g. materials with lmb nothing is displayed ( please see attached pic.). Other options like lights are working. I am using vray as render engine.
Hi Andreas- panels which are tied the Rhino's Renderer Devlopoment Kit do not show if there is not a compatible renderer current. (I suppose they should not even show on the list, I'll see about that.) VRay does not use the RDK, or at least not enough to access those panels.
