Shadow Artifacts

I am receiving these artifacts in the editor and in game. Any thoughts on how to fix this? I know I’m not giving much information about my setup, but if anyone can offer a general idea it would be helpful. With so many settings having to do with lighting, I’m not even sure what information would be needed to diagnose the problem. Any guidance would be appreciated.

no information? so… we guess?

i’d guess you got megalights on? this is what those artefacts look like. i’ve seen that. you’d have to dial in your post processing settings and lower the (auto-) exposure or go manual to lower those artefacts. megalights has a limited numerical precision. it’s not a flaw. but… you gotta dial in how much you expose and stretch this color range in post. : )

Thanks for the response. Sorry I wasn’t able to give much info since I new to lighting. Since I had been messing around with the light and postprocessing settings based on tutorials I’ve seen I figured I messed something up along the way. I deleted the postprocessing volume and started over with the default settings. The artifacts are reduced quite a bit but are still noticeable. I turned off megalights and things actually got worse. So I am back to the default settings with post processing. When you speak of dialing in postprocessing settings, could you give a little more detail? Are you speaking of the metering mode? I currently have it set to Auto Exposure Histogram.
