Hi folks, hope someone can help me with this 
Im trying to make a pair of jeans for my character, Ive got the garments seamed OK and its looking good, but when I try to run the simulation, the "cloth" seems to get sucked inside the legs... Could this be for any of the following reasons?
A.) The solver scale is wrong?
B.) The Normals of the model are inverted, so all the cloth is draping itself over the inside of the legs?
If its A... how do I change the world units?!! I cant find out if im working in CM's or inches anywhere!!
Also should I be working on the animation of the model before doing the clothes? I wanted to get all the finickity stuff out of the way before doing the good stuff!
Any solutions or information would be very gratefully recieved!!
