I tried some free bvh files from truebones.com. one of 'em (drunk1.bvh, 500 KB) worked on aiko3le (included in c6pro content), although not on some other figures. there's a "drop figure to floor in all frames" script for animations in poser, but I dunno how to do that in c6Pro, hence if I post the animation (assuming I can get a 500-frame gif uploaded here), it's gonna be going in and out of the ground plane slightly. maybe there's some command to drop a figure to the ground plane in c6pro.
