    In Unity 2020.2.0f1 Area Light Shadowmask are broken. The same scene in 2020.1 looks correct.
    I have made a little sample scene to demonstrate this issue.
    The only light in the scene is a Mixed Area Light. Shaders are simple HDRP/Lit shaders.
    The error is very obvious on the Sphere. ShadowMask_Bug.jpg
    All channels look good, don't understand why I get this problem.

    I have the same issue with a new asset I am working on. I can't release it until this problem is fixed. :(.

    Managed to repro on latest HDRP and logged the issue.
    Thanks for reporting. You can follow it here if needed. (give it a few hours)

    Can you give the HDRP version on 2020.1 were it was working properly ?

    Hi.
    For me the issue is back in
    Unity 2021.1.0b4 HDRP 11.0.0.
    It was solved around 5 days before i tested in 2021.1.0b2 HDRP 11.0.0..

    Unity 2020.2.2f, HDRP 10.2.2 has the issue too.
