    I'm trying to port SpeedTree v6 as is to the HDRP pipeline, and I'm getting some weird artifact:

    Got no shader errors.
    Maybe anyone else encountered this? What can be the cause?

    Currently I've got GBuffer pass. Tried adding depth pass with the same results.

    This seems to be caused by clip(...). Not sure how to workaround it though.
    I've tried re-creating same shader with ASE, and got same results.

    Edit:
    Using Opaque plus alpha clipping enabled did the trick. I guess I'll stick to ASE for now.
