I have not read about Delaunay (IIUC, tri-based) mesh but I am aware of two addons on the Blender Market one of which claims to be compatible with Poser characters and they are much more reasonably priced than Marvelous Designer one is called Cloth Weaver the other is Simply Cloth Pro Both seem like if combined in a cloth making workflow could produce items at a level close to Marvelous Designer. You can find both at Blender Market I can not post a direct link since they do sell some items that are similar to what is sold here so direct linking is not allowed. Perhaps you might want to look at them.
