Sketchup and Vray Resource site created by Nomeradona is full of gems. I have joined ASGVIS, Sketchucation, and now Chaos Group forums; I have not seen as plenty as resources as this site. This site is a must to visit if you are a SketchUp and V-RAY SketchUp user.
Here is a sample tutorial from this site. How to simulate lampshade materials in Vray SketchUp
Vray double sided material allows seeing the light on the backside of the objects. Vray artists use this material to simulate thin translucent surfaces like paper, lampshades, curtains, leaves and others. Gerbe Dumahil explained in this nifty tutorial how to simulate lampshade material using double sided material in Vray SketchUp.
