    Hi, I'm struggling to get my prefab visible when viewing the target image.
    Right now it flickers or doesn't show up at all.

    I have changed both the target image and the device but with the same result.
    I'm using Unity 2022.1.15f1 Silicon and iPhone XS.

    Anyone have an idea how to fix this?

    Is depth occlusion enabled?
    If so, disable it.
    And start with huge objects maybe, maybe without image tracking to see where it starts to break

    Thank you for the feedback.
    I have updated to iOS 16 and Unity 2022.6 but that made the camera freeze.
    I am now using Unity 2022.2.0b8, so now the camera works again.

    I have disabled “Occlusion Culling” (I guess that what you ment by “depth occlusion”)
    Also I have put in 2 green objects without image tracking.
    And I am using the recommend test purposes images.

    The result is still similar

    If you are experiencing camera freeze issues on iOS, ensure that your device is updated to iOS 16.3 or newer, and AR Foundation is updated to 4.2.7 or newer (for 4.2) or 5.0.3 or newer (for 5.0). There were bugs in older versions of iOS and AR Foundation that could cause the camera to freeze.

    Hello again, apparently you just need to indicate the max number of moving images to 1 or above, it was at 0 by default. It works for me, hope this will help you
