hey thanks dudes, very informative.i was just seeing weather maya had rhino type capabilities...or rather could it handel nurbs the way rhino does. absoloutely not !!!.it takes like 2 minuites to set that kind of a thing in rhino...absolute no brainer.since the alias guys harp so much on on their nurbs tecnology i trieed it out.and as a individual artist i dont need to hassel myself with thease kind of things...i know by your replies that there are ways to go around nickeling buuut i think i'll stick to converting nurbs>polies>subd's. and finally mental ray is free for us mayans so i can concentrate more on the lighting aspect and try to hide/show what i cant/want to model again thanx a lot...very helpful replies. b
