    When I use the AR Environment Probe Manager the environment gets scanned, somewhat reliably. However objects in the room that are behind the test object get reflected as if they were behind the camera. So the scanned world is off by 180°. I noticed this was the case in tutorials as well, but nobody seemed to notice.
    Any advice?

    Unfortunately, this is a known issue in Unity. Cubemaps are assumed to be Unity world axis-aligned which is not the case in an AR scene where the cubemaps are produced in relation to the AR Session.

    That renders this feature useless...?

    The issue is bigger than this. If all probes were consistently rotated, it would be easier. But they all have random rotations, which would need to be applied to the underlying texture on a per-probe basis.

    As @davidmo_unity mentioned above, we are aware of this issue. Unfortunately fixing this issue requires a major change to Unity's graphics systems in this area (outside the scope of AR Foundation), and given that risk, the team has not yet selected this work for development.
