Can't get OnCollisionEnter to work with Mesh Collider when using Leap Motion

Question

I am trying to use leap motion to interact with a couple of other game objects. At a very simple level, I have a cube which I need to interact with. For this, I wrote a script -

using UnityEngine;
using System.Collections;

public class DoorDetector : MonoBehaviour {

    void OnCollisionEnter(Collision other)
    {
        Debug.Log("Hello");
    }
}

This should ideally display a Hello in the console on Collision, but it doesn't. I have a mesh collider applied to the body and for the hands, I'm using the RigidRoundHand prefabs. I tried applying a rigidbody (in case the prefabs don't do it already), but that did not work as well.

Try Box Collider instead of Mesh Collider and let me know if it works. — Programmer, Dec 13 '16 at 12:13
Have you set collision detection to continuous in the rigidbody? This takes more CPU but detects fast moving collisions better — Martin, Dec 13 '16 at 13:50
@Programmer I did exactly that after I posted the question and it worked. Any idea why mesh collider messes up? — Zeokav, Dec 13 '16 at 18:02

You are using Mesh Collider so you must enable Convex on the Mesh Collider.

If this does not solve your problem, simply use the Box Collider like I mentioned in the comment section.

I just chose to use a box collider. Thanks! – Zeokav Dec 14 '16 at 13:02
@Zeokav Yeah, I would do that too since it is more efficient to use Box Collider. Just wanted to show those with *Mesh Collider* how to fix the problem. – Programmer Dec 14 '16 at 13:04

It will work if you put RigidBody on that cube where is this script. At least one of colliding object needs to have RigidBody. Also disable IsTrigger in Colliders of Cube and every interactible object.
