You can import objects into MD and simulate them like they were made in MD. You can change the properties of the fabric and apply pressure. In the simulation imported objects interact with avatars, ground and other clothing. What you cannot do is sew to them. This is the big drawback right now. You cannot use them easily as 'preform' for armour or bra cups. You cannot use imported objects for buttons, clasps, et cetera.

Cool didn't know that. But yeah agree that you cant sew them will be a problem. :D
