You asking about the volume fog? Sure, new blank project, added some cube grids in the middle of default terrain, in already existing heightfog I changed only two things,density to 0.5 and enabled volumetric fog.Difference is drastic with sg.GlobalIlluminationQuality 3 vs 1. See attached screenshots.
And besides that issue with volumetric fog, can you (for regular fog) please either make eye adaptation setting for heightfog density, expose eyeadaptation in BP, or make eyeadaptation node in post material work “scene color before dof” ?. Autoexposure and regular fog do not mix well.
