Thank you so much for your help @anonymous_user_f26c856c1 @MostHost_LA !
The issue was 100% emissive and diffuse boost! I have them all set to 1 now and the artifacts are completely gone! Luoshang’s GPU Lightmass took care of the rest!
I’ve been able to take great stills of the scene, but I have one more issue. There is weird shimmering/flickering on some of the reflective and emissive surfaces. I tested it in an empty level and it seems to show up in low light conditions.
Here is a video:
You can see really clearly on the big metal “cage” thing around the bar. It’s this way on emissive surfaces and pretty much all reflective surfaces at some angles. It’s even worse from a long distance.
Has anyone seen this kind of thing before?
