I want to take this process very carefully. Eventually, I was able to fix the problem, vanilla textures are now working, and I'm going to download and install NMC's Texture Pack once again. Essentially, the mod had somehow corrupted vanilla textures.

However, when I tried to play the game, I'd have the same problems even without the textures installed. During this process, I uninstalled NMC's texture pack so I could mess around with it later and try and fix the problem. Unusually, however, the game wouldn't display default textures when it was running, instead, it would try and display the corrupted textures, meaning that most areas in the game looked like my character and all the NPCs were floating in a black abyss. It seems that, during either the download or installation of NMC's Texture Pack, certain textures became corrupted in the process. Essentially, NMC's texture pack, one of the largest texture mods for New Vegas, was causing major conflicts. Awhile ago, I created a discussion where I asked everyone how to fix my game.
