Broken Lighting Across Entire Project

I was clicking around in the Project Settings > Rendering and I’m not sure what I did but now I have zero lighting in any of my levels.
When Lighting Only is on in the Editor Window it shows my lights but when I select Lit it all goes black.

This is with the Lighting Only on in the “Lit” menu

And this is it with Lit selected

Well, I suppose you shouldn’t randomly click things if you don’t know what they do :wink:. To fix the project, simply create a new one, and copy its settings.
