Third Party Spawn GameObjects via network (Photon 2, photonview.IsMine problem)

Hello. Help me please, I have a problem with spawn FX-effects.
Here Is the situation.
I have 2 cubes (2 VR hands) which shouldn’t collide between themselves and FX-effect shouldn’t be created.

When I’ll collide the Network player, FX should be create.
I’ve made a script which do all what I need. FX works fine. When I collide the Network-player FX are created.
But! Here is the problem:
In my GamePlay(locally) when I’ve collide my cubes(my VR-hands) between themselves nothing happens, but the Network player tell me that FX-effects are created. And same situation with him. He doesn’t see FX-effect when he is collide his cubes(VR-hands), but I have see it.
Help please, what function/variable I’ve missed?

Here is the Code.

Code (CSharp):

1. private void OnCollisionEnter(Collision collision)
2.     {
3.  
4.         if (((collision.gameObject.name == "CubeRed") || (collision.gameObject.name == "CubeGreen"))
5.             && (!photonView.IsMine))
6.         {
7.            
8.             foreach (ContactPoint contact in collision.contacts)
9.             {
10.                 GameObject FxInst = Instantiate(FXprefab, contact.point, Quaternion.identity);
11.                 //PhotonNetwork.Instantiate(FXprefab.name, contact.point, Quaternion.identity);
12.  
13.             }
14.         }
15.     }
