Hello, to be honest, I just abandoned the Lumen system, because no matter what I change, the result remains the same. And it’s surprising that no one has encountered the same error (except for those who have flickering lights on the walls or ceilings, which is solved simply by changing the Final Gather parameter). And then, Lumen is more for visualization and rendering, and I will dive into games where this system is still too raw. Do you have a 1650 video card?
