Tried searching for this kind of mod, but there seems to be none, also not in nexus.
You know, the same kind of sunglare mods that were released for FO3. The vanilla sunglare just doesn't cut it for me, too blurry. Screenshots look so dull without the mod :/.

It wouldn't surprise me if you could just install a sunglare mod from FO3 into New Vegas without any extra hassle.

Yeah you could do it with the one from FO3(for the 3 most popular), you'd just need to add archive invalidation for the files because they have the same names.

Good idea. Wouldn't hurt testing it I guess. I still don't have the game but will download it soon . If anyone wants to test if they work, would be nice to know beforehand.
