Comment 1 for bug 1396486

The Deer, Duck, Horse, are showing similar results, the issue appears to be that the armature has been rescaled. Scaling bones never leads to good results in my experience. Fixing this would require unparenting, unscaling, and then setting it up again. The weights also appear to have some issues, and there are a number of deforming IK/FK bones that really don't need to be carried into Ogre. I think the cleanest and quickest fix is to retarget the existing animations onto a clean rig and see about setting up puppeting bones later.
