oh okay i get that..so the scaling is not from one character rig to another but a way to compensate for the tiny size of the poser scale...(too bad...we need an app like that). and i guess the later part means no bvh for faces but i guess that makes since since the standard for that seems to vary drastically. and i guess bvh is about bones really. wow, though...so all there is in bvh is a bunch of rotation, and translation of one element. that is neat. anyway, so if the bvh is made in poser for poser, no scaling is neccessary. thanks for the reply little dragon.
