    using "Single Pass instanced" or "Multi Pass" rendering along with MockHDM mixed lighting and Forward+ real time lights show missing lit clusters as you can see in the image below.
    the ground plane uses URP/Lit is gi static and receives ambient from a light map.
    the spot light is realtime only.
    turning of gi static does not fix it. so it looks like Forward+ and VR just do not play nicely together...

    using a simple scene with all lights set to real time i get the same artifacts.

    URP Forward+ does not support XR yet, but we are working on it. For an upcoming version, I've disabled the lighting for XR in Forward+, and added a warning in the Universal Renderer inspector (we already warn in the console, but that gets overseen easily) to make it a bit more clear that it is not supported yet.

    Can you try in 2023.1.0a21? It seems to work properly for me now.

    I am at Unity 2023.2.0a15 and Forward+ is still looking as buggy as shown above. Any news about when Forward+ will be fully supported for VR/XR?

    What versions of Unity will officially support this in VR?
