We’re exporting to Unreal Engine 4 but whenever we import the root becomes Rig. The root is supposed to be HandsRoot. Does anyone have any idea why this might be happening?
If the root of a skeleton is parented to something like a control, it will consider that control as the root of the skeleton structure. You need to un-parent it before exporting.
That is expected (but weird) behavior in Blender. The only real root bone is the armature object in object mode.
Have a look at this, I think there is a ‘fix’ for the problem
