    Hi,

    Is it possible to get the Lit Graph / PBR Graph to work with alpha cutout in DrawRenderers Custom Pass?
    If I use Unlit shader like in the examples I can get it to work but not with the Lit graph. Otherwise when pass is set to Forward with Lit it renders fine.

    Anyways the custom pass system is big improvement - it was f**king annoying to do anything custom with HDRP! Kudos to team!

    Cheers,
    - J

    Hello,

    It should be possible to render Lit objects with alpha clip in custom passes with the DrawRenderers custom pass, just make sure to override the depth test if your objects have been excluded from camera culling flags like so:

    Hi, I can't make this work.
    In DrawRenderers custom pass, Lit shaders with alpha clipping renders no alpha clipped (opaque) faces.
    I have tried overriding the depth test.

    Since this thread is still alive and it seems I made a duplicate bug report, I will link it here:

    https://forum.unity.com/threads/dra...a-clipping-if-used-with-a-lit-shader.1378026/

    It seems to be a bug, but I got no reply to my other thread.

    Your detailed report really helps. Quite same as the trouble that I have!
