How to reproduce:
- Open the attached .blend and play the cube clicking game.
- Notice that the cube mesh suddenly becomes smooth when moved at all by the armature.
- Change the armature vertex deformation method from "BGE" to "Blender" and repeat. The issue disappears.
Why would the BGE method cause all the mesh faces to become smooth? It does not seem necessary. Can this be fixed?
