I'm a little puzzled by the documentation. For Continuous, it says: Why only static MeshColliders? What about the others, like a BoxCollider for instance? For Continuous Dynamic it says: ... so, again, no word on non-MeshColliders. A little later it says: ... so ... is Continuous on a Rigidbody with a BoxCollider that should collide with other BoxColliders enough? Or do I need Continuous Dynamic?
