    Hello,

    I have made a little test scene, where I can switch between a normal camera and a VR camera by pressing a key.

    I start in "non-VR" mode. The desktop shows me the "non-VR" Camera and the Oculus Rift is black. Perfect!
    - VRSettings.enabled = false;
    - VRCam.SetActive(false);
    - MenuCam.SetActive(true);

    Now I press a key and the desktop shows me the VR-Camera. Also the Oculus shows me the VR-Camera and I can take my Oculus and use it as expected. Perfect!
    - MenuCam.SetActive(false);
    - VRCam.SetActive(true);
    - VRSettings.enabled = ftrue;

    Now I want to go back from VR to nonVR (like I started the game). The desktop view now shows me the nonVR Camera as it should and also the Oculus isn't working anymore, but the Oculus screen did not turned black, it freezed at the VR Cameras last frame (or one of the last frames).
    - VRCam.SetActive(false);
    - VRSettings.enabled = false;
    - VRCam.SetActive(false);
    - MenuCam.SetActive(true);

    But I want that the Oculus screen turns black when I disable the VRSettings, because I think its very misleading for the user, if the Oculus shows one stiff picture but should not be used at this time.

    I hope someone can hel.

    Regards

    Hey, just an untested idea but maybe you could try to use "VRSettings.loadedDevice", something like "VR.VRSettings.loadedDevice = null;" ?

    Thanks for your reply and idea, but I doesn't work in my case.
    In Editor playmode the playmode cancels and in a build application the game crashes.

    Anyway thanks for your idea. I am open for new ideas too :D

    Regards

    I noticed another strange behaviour.

    When I hit play I see my normal Camera. Than I hit return and I am changing to the VRCamera. I see the VRCamera in my Rift but the picture is freezed (no headtracking and no screen movement; also on the desktop).

    Than I have to click with my mouse on the screen and than its not freezed anymore. This happens only the first time I change from the "normal" Camera to the VRCam.

    I don't no what causes this? Help would be awesome.

    EDIT: In the finished builded game, the game minimises instead of freezing. When I than maximize again, everything is good. This only happens in DirectMode!

    Regards

    @_Beyond_ Given the current solution that you have, if you want the Oculus to have a black screen, you need to clear the camera to black and render nothing on the final frame before disabling VR. We are also working on a fix to the VRSettings.loadedDevice crash in the standalone player.
