From my experience, this can be a complicated problem, especially if using mods like New Vegas Redesigned 3, FCO, or other mods that alter body textures.
In order to get things to work properly in my game, I have to instal the mods I'm using in this order:
- Ghoul retexture for Roberts Male Body replacer
- Fallout Character Overhaul
- New Vegas Redesigned 3
- Type3 & T6M Merge (Personal Merge of Type 3 body with mixture of T6M/Type3 Armors)
- Roberts AIO - NMM Compatible-48535-1-3
In a nut shell, install the body/armor replacer last. Also make sure Archive Invalidation is toggled on. I personally use the version of AI that's integrated into Mod Organiser. If that doesn't work, might be worth posting the list of mods you're using. On the very rare occasion I've had this problem because a plugin was overwriting something my body replacer was; linking the mesh to an incompatible body texture.
We'll get to the bottom of this
