I'm working with DirectX's animation system, and am working with a couple of different animated models. My problem is that in my engine, one of them animates properly and the other one doesn't; however, both of them animate properly in the DirectX mesh viewer! What's really frustrating is that I can't find any information on *why* this is happening! When I debug the code, everything appears to be working fine - in the mesh not animating, it finds the animation I try to play, and tries to play it like normal without any issues. However, it doesn't animate, and doesn't produce any errors, either. I've tried running D3D in debug mode, but that hasn't produced any explanation either. Is there a way I can figure out what's going on here? I can post the two meshes if necessary.

Have you tried running your app through Pix to see what's going on?

Actually, I feel pretty silly. This new animation is using skin animation, which our engine isn't supporting fully yet. Oops :
Thanks!
