Fallout 4 Mod Thread
It's not a mod but there's a lot of useful information here.
Turning off the 'God Rays' was one of the first things I did. I hate any sunbeams or lens flare effects in my games. Once, I actually asked CrommCruac how to disable the lens flare in Lost Alpha, which he explained how to do, not knowing until afterwards that he was the dev who put that in the game. 😳
