patch model stitched?
 

Ok, I'm finally going to ask the question that I have always wondered about for about a year now: Do you stitch every piece of a nurbs patch model together when you're done? I must admit that I've never seen anyone do this and have only seen tutorials about the actual patch modeling process to make a model, but obviously if you try to rig a nurbs patch model then deform it, the seams of the model where the patches are go crazy.

If so, what kind of stitching is needed? Global?

usually a global stitch works just fine. as for the seams when the surface is deformed, it's really a matter of where you place your patches. usually the patched model has the seam on the bones not the joints, or where there will be least deformation. like a head usually does not have sea,s at the corners of the mouth etc...
