You may also want to study the Wardrobe Wizard. It appears to me the techniques used there could be applied for what you want, to some extent. Unfortunately I will have not time to search these these things out myself until I retire, 25 years from now... For the bulges you may want to look at using a displacement map, allowing you to define the local deformation of the skin independent from the local grid definition. Anyway: have fun! B.
