My question is the one that comes in the title…
Does Lumen work well with real lux endirectionalLight values? (UE5 ea & preview 1 y 2)
I have been having the problem that I report in this forum thread (Thread). And after doing all the tests I can think of, I’m starting to believe that it’s a Lumen bug that doesn’t work well with high Lux values for DirectionalLight in rooms where no light enters.
The problem is fixed when I go down to lux values of 10, 15, and so on. when I go up to values like 150 or of course 130000 lux, the problem appears.
I have tried to change meshes Nanite and non Nanite, materials, meshes, make the walls thicker, etc… nothing solves it.
Can someone tell me if it’s a Lumen bug or am I doing something wrong? I can’t think of anything else to try.
