I have been plagued by this issue for as long as I can recall. I start my scene, save it, exit, come back and the shadows and lighting darkens. Soft and hard shadows are the exact same and Unity rendering loses what little decent rendering effects I can make.
I recently started a complete fresh install of Unity removing all cache files and very careful adding project files one by one hoping this problem may go away. It has come back.
From what I can tell, when I open a scene, the shadows go dark for a brief moment then go back to normal. However, if I move in the editor during the time the lighting is dark or loading or whatever, the scene stays dark permanently.
I don’t know if anyone else has experienced this or there is a solution. It can be slightly fixed by changing skybox shadows but the quality looks awful.
Would love to know if anyone else has a solution or knows what is going on.
I added the broken lighting and the normal lighting. Both scenes are using unity default presets.
