Hey everyone. I’m trying to make a damage system do an object. I have 3 render meshes and 3 colliders meshes(Both MeshFilter and MeshCollider Components are in my object), but when I call them with this script:

```
switch(curMesh) {
		
	case possibleMeshes.undamaged:
		
		Mesh newMesh = damagedMeshes[1];
		GetComponent<MeshFilter>().mesh = newMesh;
		Mesh newCollider = damagedMeshesColliders[1];
		GetComponent<MeshCollider>().sharedMesh = newCollider;
		
		break;

```

}

Gives me an error in GetComponent.mesh = newMesh. The error is : ‘Object reference not set to an instance of an object’. I don’t know what to do anymore. Somebody can help me?

Thanks from now!
