I've noticed that the program creates files for races, genders, and ages.
then inside the files it names the pictures based on hair, ass, and chest size. (missing flat and masc by the way :c, and no, I don't stuff my bra! you stuff your bra!)
in other words. this is an example of what the program will name files: Blond SkinL TitsM AssM #Maid 1.png
(#Maid is one of my pack tags, much like what Master Kazama is doing with "£")
The game itself seems to not pick up on file names, well, some of them anyway, while male's are getting female portraits, and occasionally a race wont be correct.
It seems the game does not register the file names as a tag to search, i dunno.
