Just my - 2 cents but... I think he's asking about BVH's There the text output of motion capture data.. Poser has a inport for them. And I think maya dose also the only problem is you have to tell maya what the channels are, and ware they conect. you also have to remove the Header data in BVH's so it dosn't get confused. Haven't attempted something like that though.

PLEASE corect me if I'm wrong.
