I've read a bunch of posts and am still having problems. I model a single mesh guy and add a biped and animate the biped (did it both by hand and with automated walk)Then I export to .fbx 2006.11.1. Then I go to med and import model from fbx 2006. The guy and his texture look great, but no animation.
If I remove the biped and just animate him moving around, it works. So, it is something with the biped part. I used skin and not physique, too.
Thanks,
Gumby
