I'm starting out again with low poly and I always had this doubt even though it's usually ask but usually a not complete answered is given.
If I have a naked low poly model and I want to add a shirt it's impossible to not make it clip throw the body? how do games manage to avoid that, do they hide the body underneath with a scrip? And if later they add an something like a vest over the shirt, do they hide the parts where the shirt would clip closer to the shoulders? If for example the character has to lean forward isn't the vest and shirt going to clip a lot if they don't have the same topology loops?
I hope I'm not confusing anyone with my question, it's my only pain when I deal with low poly, wtf do I do with clothing, wtf do I do if they ask me for a naked character that later I'll have to add cloth, the only thing I know is that I have no clue how people do it, usually the answered is something like they change the body mesh but is that optimal?
