I see that Biovision BVH is now up for download. I got a "biped" version from E-Motek to load but no animation. I've already let him know. Either the program doesn't like their format or I don't know what I'm doing. Motek offers tons of cheap motion capture(for commercial use...otherwise it's free) and it would be great to use them with fragMotion.
