Well in the case of a robots arm (modified cylinder) you are pretty much making what you described as specially constructed geometry.
Personally I have not had much problems with this, other than trying to use imported geometry from Autocad. Sadly, rebuilding is always necessary it seems.
I must admit I have never tried to render a plane primitive with an anisotropic metal shader, but I get your comment about its normals.
The issue of replacing the gradient with a fresh identical one is interesting. I'm curious to know if this is indeed a 3dsmax issue or a VRay problem.
