Bumping this. After extensive searching, I've still not found how to transfer faces from multiplayer to single player (or vice versa, but I only really care about MP -> SP).
I can export a single player character and see two "face_key" variables in the .txt file, but have no idea what to enter there.
I can open faces in edit mode and copy the face code, but don't know what to do with it.
I've opened profiles.dat but it's a big bunch of hex, and I don't know what I'm supposed to be replacing with what. I'm pretty sure that's only multiplayer info though, so I probably don't need to replace anything there.
So yeah, any help would be much appreciated. How do I copy the appearance of a multiplayer character to a single player character?
EDIT: I just found
this page which has a script on it for translating face codes into 2 face_keys. The face keys it provided contained most of the right face data for the imported character, but not skin, hair, age, beard, or some of the face settings. Closest I've found though.
