I usually don’t get this error with primitive objects(cubes, spheres) but when I import my own object, this shows up:
Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported in Unity 5.
Convex collider doesn’t work for the object since “user-provided hull must have less than 256 vertices!”
Kinematic rigidbody doesn’t work either because it no longer simulates physics. How do I make my own object to follow the laws of physics?
