Code:
(try_begin),
(store_random_in_range, reg1, 0, 18),(store_random_in_range, reg2, 0, 24),
(face_keys_set_hair, s1, reg1),(face_keys_set_beard, s1, reg2),(face_keys_set_age, s1, 0),(face_keys_set_face_texture, s1, 4),
(troop_set_face_keys, "trp_tcc", s1, 0),
(try_end),
(try_begin),
(store_random_in_range, reg3, 1, 8),
(face_keys_set_hair, s2, reg3),(face_keys_set_beard, s2, 0),(face_keys_set_age, s2, 0),(face_keys_set_face_texture, s2, 4),
(troop_set_face_keys, "trp_tcc2", s2, 0),
(try_end),
(troop_join, "trp_tcc"),
(troop_join, "trp_tcc2"),
it's in module_game_menus at the menu option right before it sets you into the worldmap, however the face texture is still the same as the player's face texture in every playthrough
