I export a poser 8 skeleton from poser 8, import it to iPi, track the motion, apply jitter removal, and then export it as a .bvh to poser, then i import it to poser. the motion isn't as smooth as it was on iPi, but that isn't the problem. When the motion is played on Poser 8, it looks like the skeleton is pinned at the hips to the wall, there is no background and the skeleton just floats there doing the motion. how can I get the skeleton to walk across the screen as if there is a floor instead of just floating in mid air?
