PaQ thanks for your reply, I'm aware of all that I was just hoping some kind of improvement have been done between Nurbs modelers and painting apps.
I just fund it counterproductive that I have to redraw a mesh with correct topology in top of the original is the worst part of the process in my opinion. So I wanted to know if anybody here use some different
approach.
Anyway within few lines you describes the hole process in a very informative way.
