The collision tolerance is the default I basically just turned off selfcollide and set stretch type to spring. I'm just trying to feel my way through the parameters.
This posting I lengthened the sleeves and trying bending the arm more. I should note that the shirt is assigned to the neck bone and I used the attach group (see flag tut) as the neck hole and the top of the holes where the sleeves start in the armpit area.
I will adjust the collision tolerance tomorrow night and get the sleeves tighter.
