Destroy Model with trigger to working

I'm using the oculus FPS character control along with a character collider. I have a paths of arrows that i want to disappear as soon as the character goes through them. I imported an arrow ( type FBX) file, i added a collider script that that destroys itself onTriggerEnter. For some reason it doesn't seem to work. I replaced the arrow with a regular cube and that work. Can some one please tell me what is going on? The object is called arrow and it has a child called mesh1. I have attached the inspector properties for both. Thanks!!

My code is the following:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Arrow : MonoBehaviour {
5.  
6.  
7.     void OnTriggerEnter( Collider other){
8.  
9.         Debug.Log ("it works");
10.         Destroy (gameObject);
11.  
12.         }
13.  
14.  
15.  
16. }
17.  

 

Mesh colliders are tricky — you've claimed it is convex, but it's an arrow shape, so probably not convex. I don't know if that's the problem, but it well might be.

For this application, I would think that a box or sphere collider would be fine, and more reliable.

 

That was exactly the problem. I switched it to a box collider yesterday and it worked fine.

Thanks!
