I've recently started modding my NV, and everything went alright once I started working on the visuals, environmental and gameplay side of it.
My biggest problem, however, is when it comes to the bodies and characters.
I have installed this body and armor replacer http://www.nexusmods...as/mods/45505/? (T6M Equipment Replacer NV) along with the http://www.nexusmods...as/mods/34702/? (BEWARE OF GIRL Type 3) skin. I'm also using http://www.nexusmods.com/newvegas/mods/45640/? (Fh hairs for fnv and fo3 conversion).
By then, I had 2 problems - the default body shown was that non-nude one, even though I never opted for it, anywhere... The other problem was that regarding the ridiculous mismatch in tone and texture between body and head.
At first, I manually changed the femalebody nifs for the nude one, and that fixed the non-nude body, although now there's a small gap between neck and body.
I had previously tried the Mojave Girls and the Mikoto beauty pack, both uninstalled so to avoid conflicts with anything.
I'm using NMM and made all the necessary changes and fixes regarding archive invalidation also on the .inis... What can be causing this? I really didn't want to have to reinstall everything from scratch since it seems to revolve only around the characters/bodies...
These are some of the screens and mod list:
