woa, u don't have the bonus tools yet??
get it and quickly.
u can "draw a split" over a polygonal sruface. yes, simply drwa a curve on a poly surface and it will slpit across edges, oh man, they added loads of crap in there. many script and a good niche of texturing tools and a "poly nurbs projection" dunno how this works, but i hope it gives a poly UVs automatically like a nurbs and u can simply project a texture file onto it.... i could be worng tho...
dwnld it now, it's gr8
