heyas; i messed with it a bit. btw, the trans-mapped hair does not HAVE to be double-sided. in fact, i can't render double-sided meshes in p4, anyway. now in order for the cloth hair to fall, fold, and collide properly, it needs to be pretty high-res. to get any decent depth with trans hair, you need several layers. okay, it isn't 20,000 strands with 20 points each, but the vertex count starts getting up there. the strips/plates/layers/whatever you want to call them; they can't start inside the head, or intersect any of the mesh of the body you want to drape it on. haven't tried making it self-colliding, so i don't know if that is better, or how much longer it takes to do all that. that's about as far as i got, my hair looked pretty crummy.
