This may be a pretty unusual request. I'm looking for existing clothing items with a "non-manifold" mesh, which means that it has edges shared by more than two polygons. I'm told this is not uncommon in dynamic clothes with features such as sewed-on pockets or ruffles and such, where the unusual topology is necessary so that the garment does not fall apart in simulations. If anyone has, has made, or knows of such items, please let me know. It doesn't really matter for which figure.

The reason I'm looking is that I've made a Python script that can fix the vertex order for morphs (see this thread). The original version only supported manifold meshes, but now I've extended it to non-manifold ones and am searching for "real-life" non-manifold examples to test it on.

Thanks in advance!

I don't see why your algorithm couldn't be tested on any non manifold example mesh, I doubt the math is so specifically discerning of form. You can make one in about 5 seconds by extruding edges. Or more complex shapes if you prefer with a few minutes.

I’ve tested it on some examples I made in Blender and also on Apollo’s eyes. Unlike the manifold case, the math I ended up using is specifically discerning of form, though. Even if it weren’t, real life examples are good because they have a way of showing me possibilities that I’d forgotten to take into account.

No matter, I’ve moved on.
