    I would like to render a seperate camera for the screen and one for the HMD.

    I turn on VR mode, and configure the cameras accordingly, then manually disable mirroring via code.

    The result is the primary camera rendering correctly to the HMD, the secondary camera is rendered to the display but is however stretched horizontally.

    I am running the latest 5.3.2p1

    Hi,

    This is expected behavior. When you disable mirroring via code you should also Reset the FOV. When we recognize that a camera will be rendering to the HMD we immediately set the FOV to the FOV of the target headset. So initially we think that the secondary camera will be a 'VR camera' and we set the FOV accordingly. So when you set the secondary camera to render to the main display we don't know what to do with the FOV. Anyway, reseting the camera FOV should fix that.

    If you're seeing a different issue entirely, let me know and I'll dig into it.

    Thanks

    Thanks for the quick reply on this.

    Unless I'm doing something stupid (quite possible!) then I've still got a problem.

    Even after messing with the cameras fieldOfView setting I still have a vertically squashed image on the main display. Below is what it looks like.
