is it possible to instentiate a projector on the position you hit an object and just project a texture of a bullet impact? I don't know anything about projectors but thought it is maybe possible?

Why do i get this error when it collids?:

NullReferenceException: Object reference not set to an instance of an object

bullitHole.OnTriggerEnter (UnityEngine.Collider hit) (at Assets/bullitHole.js:3)

I used this code:

var bulletHole:GameObject;

function OnTriggerEnter( hit : Collider){

var hitRotation = Quaternion.FromToRotation(Vector3.up, hit.normal);

Instantiate(bulletHole, hit.point, hitRotation);

}
