From what I understand, when you're editing your appearance at the beginning of the game, at the bottom of the screen a "face code" is generated. This "face code" consists of a string of text that represents the details of your character's face. For example, this one possible face code:
The above face code represents the following face:
This is an extremely convenient way to share your character's appearance with people, but it's not so convenient to access. For all I know, the only time you can access this face code is during the appearance editing process. If you wanted to share your face with someone after leaving that interface, there is no way to do so. But this is all, again, "for all I know"...
Is there a way to access your face code after leaving the appearance editing interface at the beginning of the game?
