I’d like to register an issue here about lumen reflections.
The editor screen started showing black squares at certain camera angles and excessive glare in some parts during rendering.
At first I thought it could be a cause of bloom or lens flare, then I disabled both and nothing. My Post Process Effects is set with Lumen reflections, “hit light for reflection” and high quality thinking. This issue appears to be related to the “hit light for reflection” option. After changing it to “surface cache” the black squares disappear. it’s weird, in UE5.0.3 this didn’t happen.
It might help someone who is experiencing the same problem.
Let me know if there is another solution for this. Thanks.
Yep, same issue, I was advised it was lens flare-related, so I set my global post process volume to 0, and it significantly helped reduce the black boxes, but has not gotten rid of it completely.
This is how it looked before
Any real fix for this yet? In my case it seems to be bloom that’s causing it as I disabled it and my render was fine, thing is I really want the bloom effect. Any ideas on a fix?
I figured a workaround for my movie sequence which might help others dealing with the same issue, and that is the set key frames to automate the bloom intensity so the effect is only active when I actually need it, as strangely it only effects the sequence in places where you can’t actually see it, I’ve not done the whole render yet but it looks promising.
If it turns out that it happens on frames where I need the bloom effect I’ll see if I can do two passes, one without it and one with and mask them together in my video editor, a pain but that could also work.
