    Hey,

    we are using HDRP and are getting this error for "bigger" scenes. Some side notes: we recently upgraded from standard pipeline to UDRP and then to HDRP. This error leads to a static image because it won't render anymore. The game still runs in the background though.
    We want to pitch our game in a few weeks and any help is appreciated. And I know this isn't a lot to go off.

    Thank you for reporting the issue, this seems to be related to an issue on shadows map set to either on Demand or onEnable as update mode. Of course it is not expected, if you could file a bug with a repro project would be very helpful in tracking and solving the bug.

    It looks like the caching system of shadow map is failing in your case.

    In the meantime some things to consider:

    - Increase the maximum number of shadow requests that are allowed. You can find this setting in the HDRP asset you are using. Though I am not sure this would be a sure fix since I don't know what the core issue here is in this case.

    As a (sadly expensive) workaround you can reduce the number of shadow maps that are set to OnEnable or OnDemand as update mode and either set them to not cast shadows or if you can afford it set it as real time update.


    Unfortunately without a repro project is hard to understand more what is going on. If you could provide one as part of a bug report it would be much appreciated.

    @francescoc_unity I'm having this issue as well on 2019.3.13f1.
    Just updated from 2019.3.6 and yeap this issue is happening. My project is too big to send. So can't really help much on this front.

    Not sure if mine is any different than his/hers but here's my error output.

    @N1warhead francescoc was nice enough to help me in direct messages.

    What worked for us was to change lights from Update Mode "OnEnable" or "OnDemand" to "Every Frame".

    @ayellowpaper Thank you, but unfortunately it boggs my PC down with 25 point lights even with a resolution of 64.. I really wished there was a GI solution for HDRP, I'm having to use point lights to give some slight environment lighting for glowing mushrooms.
