@Nguewt It really needs a way to position the garment to achieve certain wrinkles, and then tell MD to try and maintain those wrinkles to some degree even once returned to a relaxed pose. And it needs options to set friction between garment and avatar. Trying to roll up sleeves and have them STAY rolled up is a nightmare.
Hell, I'll just come out and say it: I don't like Marvelous Designer that much. Obviously the technology is amazing, but it's just not advanced enough yet to be worth the hassle. At least for what I want out of it. Do I really want to spend an hour painstakingly battling it's collision and simulation just to loop a neck…
