I have a half ring, I and my character to be able to jump inside the ring - however it does seem like this is possible since the collision editor doesn't allow it? I wanted the ring to be a physics object so the character can move it - sort of like a vehicle so I can't use work arounds or anything. Please can someone confirm if this is possible or not?
I don't know if it's the best solution, but you can use several objects invisible attached to your ring as a collider.
