I recently experimented with lighting in my project, however, to my regret, it did not end well. I came across running shadows, the appearance of some lines of light on the walls closer to the ceiling. Also, when I optimized the project somehow, namely by the drawing distance, when you quickly turn the camera, you notice that some lines appear there.
It does not look like the work of the denoizer, because it is turned off (and almost many similar functions have become inactive), besides, the lighting selection buttons in the Post Process Volume have become inactive after a couple of re-entries into the project. I dabbled with almost everything that is possible in Post Process Volume Lumen GI, in the end it turned out what happened, and it did not work out to make a normal exposure
Help, please
I will attach screenshots and videos below
