So I've been using Outfit Studio to add bnb to some outfits for FNV in the same manner that I became accustomed to when modding Skyrim. Outfit studio makes it really simple, you load a ref, load an outfit, then copy the bone weights from the ref to the outfit and bingo, instant BnB.
However occasionally for reasons I cannot understand this breaks the Nif in a peculiar way. From a distance everything is fine, the outfit looks normal, the breasts jiggle as intended. However as soon as my character get within a certain distance, parts of the outfit become invisible, returning to visibility once I back away again.
Can anyone point me in the direction of a possible remedy for this, or at least tell me why it is happening?
