title: How to stop Vuforia Behaviour
body: <p>I have three scenes in my project.</p>
  
  <p>First one is just a Main Menu.</p>
  
  <p>Second one is a Virtual Reality Scene using GoogleVR</p>
  
  <p>Third one is a AR Scene using vuforia.</p>
  
  <p>Not sure why, but when I started VR Scene (Not AR), vuforia behaviour is loaded too and it changed my field of view.</p>
  
  <p>There is a way to prevent vuforia to start when app is loaded and just start when I load AR Scene?</p>
  
  <p>I tried this but not worked. This stopped the camera instance, but not vuforia behaviour.</p>
  
  <pre><code>public void stopAR(){
      if (Vuforia.CameraDevice.Instance.IsActive()) {
          Vuforia.CameraDevice.Instance.Deinit ();
          Vuforia.CameraDevice.Instance.Stop ();
          Debug.Log ("AR Stopped");
      }
  }
  </code></pre>
