Tried the regular UUNP BS but they fail to generate since there are no files(.nif) and some of the BHUNP armors(Book of BHUNP, Bad Dog) I give to my Bijin modified followers don't fit well(larger than normal breasts and invisible wrists). If not possible or too time consuming I'll just leave well enough alone. And yes I did select UNP body during installing the Bijin mods so it's not a CBBE related issue
