A bit more detailed explanation... I am using a mod (Vilja, if you know it) that has a separate mod (sort of a mod-within-a-mod) that allows the NPC (Vilja) to have its own body. Basically, a standalone mod. I built this instance of Skyrim as basically CBBE everything except for the Vilja NPC - I used the sevenbase body, with Barbarian and Milkdrinker's barbarian skin textures. OK so far? It works, no issues, until it comes to clothing / armor. I give the Vilja character UNP based clothing / armors, but... when she changes outfits, there is quite a bit of clipping until she changes cells... And next outfit change, lather, rinse repeat.
Any comments? Questions? Suggestions?
