What's wrong with UVs ?

 From:  jbshorty
@ Knightxor - As Michael explained, the UV's of a Nurbs surface do span exactly from 0,0 to 1,1 but they are spaced according to the density of isoparms in the surface. So where you have a relatively flat or stretched area it might have expanded UVs and where you have more isoparms (to hold a tight curvature) then you might have compressed UVs. In other programs you might rebuild (or reparameterize) a surface, thus increasing the # of isoparms and also spreading them evenly by distance in the U and V directions. But the shape of the surface also changes when you do this. Sometimes you have to give up one thing to gain something else... But I am totally with you on the idea of UV nesting. In fact i requested it myself for V2...
