I have indeed at last found a way and a workflow that works, with C4D and the Mocca module with some scripts. Marvelous Designer will never be able to deliver a quadmesh, for the simple reason that no one else have. (delivered a good enough tri to quad conversion that is). So where is the people using retopology? After all it is a quite useful thing to have in your skill set not only for Marvelous Designer but also for cleaning up sculpting models and the like.

So how do you go about it? Is there a better way? Anyone tried Polyboost plugin for Max?
