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.
Often I see stuff like this when the light radius is too large or going through geometry.
I actually solved it. I wanted a bright atmosphere for an indoor scene so I really cranked up the intensity and attenuation of my lights. I also had the exposure in post processing set to high. That were a result of watching too many tutorials. I achieved the goal of a bright atmosphere but the cost was the artifacts. After deleted the post processing and adding a new one, I did some research on the natural lighting temperatures for offices, kitchens, hallways, etc. and used those on my lights instead of changing the color. I then lowered the attenuation to only what I needed and increased the intensity to the brightness I wanted. From there the artifacts came back but not nearly as bad. To get rid of the remaining ones I turned on Exposure Compensation in post processing and turn it down gradually as glitchered mentioned above to get rid of the rest. The result was a much more natural looking scene. Since lighting seems to be a black art to me, I’m not sure if my approach is the correct, but it care of 95% of the problem.
