Tutorial V-Ray for SketchUp - Bump and Displacement on Curved Surface.

REMEMBER : You need to the UV coordinates 100% right to avoid gaps when displacing irregular geometry in this sample. Note by thomthomp Notes on displacement in VfSU 1. Always isolate the geometry you want to displace. If any displaced mesh connects to other mesh with different materials it won't work. 2. Displacement takes lots of memory. You can quickly run out of memory with this on. The larger the face your displace, the more it needs to keep in memory while it processes that face. Avoid large faces and sub-divide if necessary. 3. Displacements increases rendering times. Don't use it unless you actually see a big enough difference. Quite possibly a bumpmap will do the job instead.
