Unity the animation is very slow, and I don't see anyplace to speed it up. I had to scale the mesh up by 100, wonder if that made any difference.

The fbx is also marked 'read-only' and I can't delete the extra cameras and lights or edit any of the animation, even if there was a speed control, which I'm not seeing. Another fbx import from messiah worked just fine.
