Underwater Realism

[TML340]

I was swimming in the river (I forgot it's name) connected to Lake Mead and couldn't really see anything above the surface because I have really dark nights enabled from Nevada Skies, and when I dove underwater I could see way too good, and I thought of how dark it should be. I thought that, in order to see underwater, you'd have to use either your pipboy light, or an actual flashlight, like the NVSE flashlight mod, which I found works well underwater, it's just not necessary because you can already see fine. So I searched for a mod on the Nexus that did this and I couldn't find one. Although I did find a nice mod that adds "godrays", or light rays, underwater and makes it blurry unless you're wearing goggles of some sort. It's a great mod but I didn't find what I was looking for. All the mod would do is change the world darkness or something when you submerge yourself. So if anyone is looking for a good idea of a mod, I think this would be a pretty simple idea (cause I don't know how to do it) and a great change to underwater exploration.
