everytime I build the lighting and jump into the level, every light source only gets to the wished brightness slowly like a dimmer. I don’t really know why this happens, because I never had problems like this with the other editor versions…
This is likely from the automatic exposure control. There may be some light that is “really bright” which only exists at the start. Or it may be that the game automatically starts assuming everything will be bright, and then ramps it up when it isn’t.
This is also called “Eye Adaptation” and you can read more about it here: Auto Exposure (Eye Adaptation) | Unreal Engine Documentation
