Unity Google Cardboard persistence

Question

I have two scenes in my Unity 5.1 project. The first does not have any cardboard reference in it, it's a Vuforia AR scene. When I click on an object it loads the second scene.

In the second scene I use the cardboard SDK to track the device rotation. I don't need stereo. I only use these commands:

Cardboard.SDK.VRModeEnabled = false
Cardboard.SDK.UpdateState();
Cardboard.SDK.HeadPose.Orientation;

The problem occurs when I load the first scene back after the second scene. It seems that the Cardboard SDK persists and it hides the AR Camera. I get a black screen instead of the camera view.

I tried putting

  Cardboard.SDK.VRModeEnabled       = false;
  Cardboard.SDK.EnableSettingsButton    = false;
  Cardboard.SDK.EnableAlignmentMarker = false;
  Cardboard.SDK.enabled = false;

before leaving the second scene, and at the start of the first scene, to no avail.

Any help would be appreciated, Nir.

are you observing any Game object (a prefab of Cardboard) created automatically in your first scene ?? — Ankur

This problem should be fixed in the latest version (0.5.1) of the Cardboard SDK.

Another way to tackle it (if you don't want to upgrade, or it is still a problem) is to add a Cardboard script to an object in the first scene, and set its "VRModeEnabled" property to false.
