I upgraded the engine in my project from 4.24 to 4.26 and the lighting changed dramatically especially in darker scenes making the game unplayable.

4.24 scene:

4.26 scene:

(screenshots are taken from the editor and it looks the same eg. on Xbox build)

Is this caused by changes in the lighting model or could some project setting get changed in the upgrade process?

I fear that I will have to manually adjust lights in all scenes:((

so the problem was this

the autoexposure has been changed in 4.25 → I have to manually adjust the postprocessing-autoexposure settings in all scenes
