I have a scene with a strange bug - when I press simulate - sun appear just a white cicle without effects, and after stop it’s still the same. But after project reboot - in editor all ok before press simulate - again and again.
I migrate this scene into blank project and create new level - EMPTY . I copy sun, skylight from this level to old scene (which I migrate), and on the old scene I delete anything.
please, see it:

On the EMPTY level all is ok - in Editor, in Simulate mode - sun is good.
But if change map to ApartmentCUT (migrate map) and press simulate - sun ugly again.
and if change level after it to EMPTY - sun ugly there too.
If restart project - all ok before press simulate on migrate level.
IF it’s not a BUG, I very very appreciate explanation how this magic work.
