Here is the "opaque" render (I quoted nudity even if the shirt is completely opaque!) . With DS4, render in Octane and of course VWD! (GPU version). VWD is a major tool in my workflow. since a long time and I think I only master 5 % of the possibilities

VWD is not a one click solution but the more you invest the better are the results. It has been a long time I didn't read again the manuel :-) ! Did you get some results with your plane and cube?
