I don't understand. It's not possible to create new NPCs with face textures that are correct? How did Bethesda make the ones that are already in the game? The creation kit was supposedly hyped as the same creation tools they use.
Because Beth's NPC are all in Skyrim.esm. If you edit a vanilla NPC (either in the CK or the NPC editor) it creates a mesh file in \Data\Meshes\actors\character\facegendata\facegeom\skyrim.esm. If you create a new NPC, it puts the mesh file in it's own folder.
I also found that when you modify an existing NPC, the mesh file name that it creates matches its ID. I'm trying to create an NPC and in the CK, the ID is 010006d2, in the game the ID is 6700006d2 and the mesh file that is created is 0000006d2. All different.
