I'm trying to get my first 3D game done with Unity. In this game the character will be flying through some rings.
I made the ring asset with MagicaVoxel, exported it in .obj and reimported in Unity withouth problems. I've set a rigidbody and a box collider on the character model and a mesh collider withouth rigidbody to the ring and I've also set Convex and added the default mesh of the ring.
The problem is that whenever I try to go inside the ring, I can't because I collide even with the empty part inside it. I'm not sure on how to made Unity collide only with the external part, but as far as I can see in the editor I'm using, I've no setting for it. I'm using Unity 5.3.4f1.
Can someone please explain me how to solve this problem?
Thank you very much.
I'm sorry, I forgot to mention that I'm aware I can unset the ring mesh Convex property and get it to work. The problem of this solution, though, is that whenever I put adjacent rings I can glitch through them even if there's no space to fit. So basically I need a solid collider with Convex only on the external part of the ring and with empty space to fly through on the inside. Is this possible somehow?
