Yeah the body model they used in FFXV doesn't have topology for the nipples and bellybutton and instead just uses a normal map which is pretty common for games... SEVERAL GENERATIONS AGO XD FFXV's game engine can handle a ton of polygons so adding some more for better body detail wouldn't have caused any performance problems haha. Anyway I made some progress on restoring a game quality body base for Gladio to use in mods and adding actually modelled nipples and bellybutton is definitely a goal (haven't gotten to that point yet though, making anything to use in mods in general is still a big insurmountable task for me these days haha).
