Replacing posters not showing up

[Doooom560]

I've recently picked up Fallout New Vegas after the great time I had playing (and modding) Fallout 3 to death. Just like I did back with FO3, I've been working on a personal poster replacing pack. Even though I had no issues doing so with FO3, I've run into an odd problem with FO:NV.

 

I've downloaded one of the few FONV poster-packs to analyze the structure and files that specifically contain posters. I went through all the files, replacing them with images of my own. When I went back to the game to go see if they replaced correctly, most of the posters and all billboards were succesfully changed. Despite this, there are still a few sets of posters that don't appear to be willing to get replaced.

 

The posters, which are still showing their vanilla equivalents, are the smaller, publicity ones (example: the Radiation King, Sugar Bombs and Abraxo Cleaner posters). You can see some of the posters in the Dino-Deelite Lobby, and pretty much anywhere else too.

 

To be more precise, file-wise, I'm talking about the 'urbanposters' files which I believe to be in Textures -> Architecture -> Urban. I have edited all files directly with Paint.NET. The poster-pack I had, had the textures at twice the size. Even after down-sizing them, the vanilla posters keep showing up.

 

The poster-pack I downloaded for reference can be found here: Lurker101s Billboard Loadscreen and Poster Pack (NSFW, was the only pack I could find that replaced everything I wanted >_<)

 

Now, what I'd like to know is why these posters are refusing to get replaced by my custom images. Any suggestions, possible solutions or questions are welcome.

 

Thank you in advance,

Doooom

You did turn on archive invalidation didn't you?

Yes, I did. If I recall correctly, Nexus Mod Manager does this automatically, correct me if I'm wrong.
