Gang, I need help with getting a lathe effect on flat or circular primitives.  What I'm trying to do is simulate a sheet metal effect.  In 3D World magazine, they use Anisotropic to get the effect.  If I give a box a slight curve and apply the node, its partially successful.  However, I want to do it on a flat surface (I'm building a virtual radio system face plate and control knobs etc). As anyone been successful at getting this machine milling effect?  Plutom
