I am currently working on a project in UE5 and wanted to test out lumen. It was a fairly heavy scene in UE4 and seems to run pretty well in UE5 with lumen, but there is one pretty bad issue that comes up.
Depending on where I am facing there is an unbearable amount of flickering. I thought it might have been because of all the foliage I had, but when I hid the foliage the issue persisted.
Also when I am looking in a direction where there is no flickering, I notice on some of the foliage that there are some splotchy shadows even if I max out the final gather settings. Perhaps that one is just a limitation of lumen at the moment, but the biggest issue I need to solve is this flickering.
Does anybody have any thoughts or ideas? I have shared a link with a video demonstrating this behavior I am experiencing.
