i checked the same some days ago, as i wonder why i only found one 3D model for each race/gender only. as example there is only one female body and all females use the same. really big differences i dont see ingame for females, so i also start thinking about a file for the scaling. maybe that info is in the Fallout4.esm or Fallout4.cdx, since i dont know what is inside. then you maybe see a large amount of premade .nif files, contain full npc bodys, eyes, mouth and so on. i think there is a difference between the player model and npc's. lets wait for the new nifskope.
