    Hi guys! Anyone knows why Unity is getting these artifacts while Light's Shadow Map is enabled? They disappear when I turn off Shadow Map. This is the Scene View but they appear in the Game View as well! ShadowTest01.jpg ShadowTest02.jpg

    Hi,

    This lack some information to provide better help.
    Which binary and HDRP version are you using?
    What is the setup? (in particular what forward/deferred mode are you using and shadow quality filtering?)
    Thanks

    It looks like something from the contacts shadows.
    If you add an override "contact shadows" in your global volume and disable them, does it still happens ?

    Hi thanks for your replies. Yes it is indeed due to the contact shadow override. If I add this override to the volume and then disable it, those artifacts get away

    This was recently added in Blender Cycles with shadow terminator parameter.
    Maybe can be useful.
