I use Marvelous to create clothing for characters that are then posed with brief (60-second) animations for rendering in still images.
For the life of me, I can't find a way to keep the collars of my character's linen shirts in place during animation. If there is an additional layer (jacket or coat), that layer always pulls the collar away from the character and severely stretches it away from the neck and down the shoulder.
In real life, the collar would stay in place and the jacket would slide over the shirt during arm movement. Here, the jacket pulls the underlying fabric with it.
Tried everything I can think of, from reducing the friction values of the avatar and all clothing layers, to bonding or solidifying the collar pattern, to attaching it to the avatar with lots of tacks or a line tack. Nothing works. Well, line tack sorta works but it crumples the collar during animation so no, not really.
What's the secret?
