MainCamera not working if I set: SetActive(true);

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class NetworkManager : MonoBehaviour {
6.  
7.     public Camera standByCamera;
8.     SpawnSpot[] spawnSpots;
9.  
10.     void Start(){
11.         spawnSpots = GameObject.FindObjectsOfType<SpawnSpot>();
12.         Connect();
13.     }
14.  
15.     void Connect(){
16.         PhotonNetwork.ConnectUsingSettings("Distructor 1.0");
17.     }
18.  
19.     void OnGUI(){
20.         GUILayout.Label(PhotonNetwork.connectionStateDetailed.ToString());
21.     }
22.  
23.     void OnJoinedLobby(){
24.         Debug.Log ("OnJoinedLobby");
25.         PhotonNetwork.JoinRandomRoom();
26.     }
27.  
28.     void OnPhotonRandomJoinFailed(){
29.         Debug.Log ("OnPhotonRandomJoinFailed");
30.         PhotonNetwork.CreateRoom (null);
31.     }
32.  
33.     void OnJoinedRoom(){
34.         Debug.Log ("OnJoinedRoom");
35.         SpawnMyPlayer();
36.     }
37.  
38.     void SpawnMyPlayer(){
39.         if(spawnSpots == null){
40.             Debug.LogError ("WTF?!");
41.             return;
42.         }
43.         SpawnSpot mySpawnSpot = spawnSpots[Random.Range (0, spawnSpots.Length)];
44.         GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate("PlayerController", mySpawnSpot.transform.position, mySpawnSpot.transform.rotation, 0);
45.         standByCamera.enabled = false;
46.         ((MonoBehaviour)myPlayerGO.GetComponent ("FPSInputController")).enabled = true;
47.         ((MonoBehaviour)myPlayerGO.GetComponent ("MouseLook")).enabled = true;
48.         myPlayerGO.transform.FindChild ("Main Camera").gameObject.SetActive (true);
49.     }
50. }
51.  

In the Unity the camera on the child of CharacterController is disabled.
So this code:

Code (csharp):

1. myPlayerGO.transform.FindChild ("Main Camera").gameObject.SetActive (true);

Must work!!! But didn't work!

 

Sorry. I realized which is the problem!!
Please close the thread.
Thanks!
