Texture pack issues

[NikoofDeath]

I'm having issues with several texture packs.

 

First, the Textures Over Time pack (although I believe I was also having this issue with "NV Terrain Recreational Project HD) is having issues with rocks (I assume this is related to normal maps?)

 

Example of the issue:

Second of all, several texture packs I installed recently (the ones by Hectrol (though http://www.nexusmods.com/newvegas/mods/39945/? is working) and Ojo Bueno Nuka Cola Machine) aren't displaying properly. Here you can see the correctly replaced Ojo Bueno Sunset Sarsaparilla, and non replaced Nuka Cola.

For reference, the Nuka Cola Machine should look like this

Note that I'm using Mod Organizer (though the files in question are not being overwritten by other mods).
