When I import clothes from Marvelous Designer I like to keep the seams of clothes that are sewed. Right now to do that is to import them as 1 object but unsewed so blender sees them as separate objects. Problem with this is that when I try to do a cloth simulation things fall apart. If I use the weld modifier, the seams are gone. Is there a way to weld them together to do a cloth simulation on the clothes (hoodie in this example) but keep the seams?
