I'm getting an annoying problem with the Rust ENB found here:
http://www.nexusmods.com/newvegas/mods/57475/?

The problem happens when I go into exteriors that are separate from the main Mojave wasteland exterior.
Places like Freeside, Camp Mccrarran, Crimson Caravan, and New Vegas. Here's what the bug looks like:

Spoiler:

Now, I'm not sure if this is a glitch or a setting that I have enabled that's causing this.
can anyone help?

Reinstall your weather mod and deactivate all Shadows in the Game. Perhaps it helps, i hope so =)

if you have the time you could also try a differnt enb to see if the issue persists if it does its not the enb's fault.

Okay, I've been wanting to try overgrowth ENB anyhow.

EDIT:

@Trunks207 Thanks man, I reinstalled Realistic Wasteland Lighting and it worked!

@lukaboot Unfortunately That didn't work, thanks for trying to help though, I really appreciate it!
