Lumen is not working in some levels, also causing strange behavier after opening these levels

1.Lumen is working on newly created level


2.Then open a level that Lumen is not working

3.Open the level just not, appeared to be Lumen is not working anymore, until restart UEEditor

Current version is UE5.1

I’m pretty sure you can’t use Lumen with static lighting. Maybe change your directional and skylight to ‘moveable’.

It is already movable lighting. Also Lumen Overview is not working which means the whole render pipeline is not correct

Sorry, my bad. I saw that red error ( top left ) and assumed it was the lighting message… :-/
