Help Cloth backside collision with box

[josemendez]

Actually I was able to find what was the problem.
I disabled collider. Not obi collider, but unity box collider. 

I am not sure if this is just natural side effect, or some kind of bug, but the result is that collision still works, but not 100% properly.

ObiCollider is just a wrapper that exposes unity collider data to Obi. If you disable the box collider, the ObiCollider should also stop working. Maybe you had another collider inside/behind the box?
