does the skeleton of a mesh moves along with the mesh like in blender, or it stay at the same place all time?
what is the difference of bone.getLocalPosition() and bone.getWorldPosition?
The bone local transform is relative to its parent bone, while the world transform is relative to the model. In other words, the name getWorldPosition() is a bit misleading since it's not in the scene graph's world space. Since the skeleton is supposed to act as a separate scene graph from the main jME3 scene graph I think its fine.
