This seems to be a common roadblock for new modders. I've been tinkering with creation kit for a couple weeks now trying to overhaul NPCs. I've wasted countless hours on failed attempts. I export my .nif from racemenu, then exporting the vanilla characters .nif from racemenu to the games loose files. I next use the NifMerge tool and merge the racemenu.nif with the ck.nif match vertex and merge. I then add hair, eyes, beard, etc through ck. When i load game. Stand next to NPC with my Race Menu Preset and... Different. WHYY!
