Sometimes I see fluctuations when I look at objects from a distance. It gets better when you get closer to it. But when you move away again, fluctuations begin. When I turn off the Lumen setting, it still doesn’t work. I don’t know exactly what it’s about. Objects are single objects. So there are no nested objects.
Changing the anti-aliasing setting to a value other than TSR solves the problem, but the quality becomes extremely bad. There is no post process volume in my scene. If I add it and change the Final Gather Quality section, it still does not work.
