Getting Animation @ system to work

Hey

As far as I know, the system works like this: You have your character mesh with skin exported as an fbx called mesh.fbx Then you have the animation exported as a different fbx file with skeleton only, and you call this file mesh@run.fbx or mesh@idle.fbx depending on what animation it is.

So i.e. you have these files:

mesh.fbx

mesh@run.fbx

mesh@idle.fbx

Unity will then automatically connect the animiation files properly to the mesh file and it should all just work.

My problem: It connects properly, but when I hit play... NO ANIMATIONS.

I've baked all the animations to the joints beforehand, so there's really no rigg. Just baked animations on joints.

What I think is weird is it worked on our first character, but on our second character there's no animation what so ever. Even though I've tried a thousand different times with different fbx settings and all that. I even tried including the mesh in both the mesh.fbx and the mesh@run.fbx files. The animations play perfectly when I import just the mesh@run.fbx with mesh and skeleton all together. So there shouldn't be a problem with the animation itself.

Anyone had this problem and know what's wrong?

I'm using maya 2012 and unity 3.5.5
