Not all joints rotate in Mecanim while they do have animation on them.

I made an animation in Maya where rotateY on all finger joints has animation. This animation is then baked in Maya and plays back fine.

When this animation is imported in Unity, there is no animation on the upper joints in the fingers. You can see the problem in the following movie:

The avatar is also set up correctly, all joints are recognized as seen here:

So right now I'm at a loss as to why the joints are not rotating while they have animation and are configured correctly in the avatar.

Any help is appreciated.
