Issue :
Sometimes in editor viewport lighting came whatever the lighting I did , sometimes it’s getting darker.
If i restart the project then it’s coming correct, not every time but most of the time . it is the same for in package build also.
used UE5.5
so far I tried some of the things that I thought it might be causing the issue , But unfortunately they are not the culprit .
which are :
Post process volumes
lights ( rect lights) & mega lights ( I’m using mega lights for this scene)
ray tracing
auto exposure
