Why? and is there anyway to access it?
because the mesh positions on a deformed armature would need to be recalculated every frame
reinstancePhysicsMesh()
or something like this updates the mesh position but it’s very expensive to run each frame
When a mesh is parented to an armature this over-rides all vertex modification you might try to do to it. You can’t set the vertex colors or positions and you can’t change the UVs or anything like that.
