So after some extensive testing, both of the FNV and the TTW versions, I've concluded that one would be better off just adding the individual mods if available into a single merged weapons plugin. Several of the weapons have low-res textures, broken meshes, missing animations, or a combination of all 3. Apparently the TTW team is going to doing some work on theTTW version so it might be worth a look further on, but until then I'd advice everyone interested to pass and instead look for better models on the nexus/internet.
