In the recent Marvelous Designer update it is now possible to make a model, UV unwrap it, then import that into MD as your cloth base. This makes it very easy to model more complex shapes then simulate as cloth rather than figuring out a way to do it from scratch in SD. It is really good for hard surface.
Will be making another mat in the future using MD and better document the new features to help show the process on here soon.

There are some other interesting features added like sculpting in MD too!
