Over the years, and they'll never fix it.

So. I'm running the Neg. It's a start at Wildwood Cemetary. These mod-breaker grift-meisters at the Bathysphere have spoken of technical boosts over and over again, but I'm in a crypt and the rain is coming in like I was standing outside of it.

 

Enough is enough. Every roof, every floor/ceiling above your head, every overhead texture that counts as coverage should block the fricking rain. Even things that drip should, you know, drip like the condensation-coated ceilings of 111! This isn't fricking Hogwarts and even the Great Hall's ceiling just showed the outside, it didn't let the rain in.

This rain blockage must be a script on all applicable overhead surfaces, deco and Workshop items alike.

ENBSeries for FO4 comes with a lot of settings for rain, and it pretty much fixes rain occlusion. Even if you disable everything else, it's worth it for that alone IMO.
