Codea Craft:Ball socket joints?

How do you do ball socket joints in Codea Craft?
I didn’t see it in the documentation. In fact I didn’t see any 3d physics joints in documentation. Future update?

@Rdo Yes this is one of the notable missing features which I plan to add very soon (Shadows, 3D Physics Joints, 3D collision callbacks).

@John was this added by any chance? I could really use that joint physics in craft
