whats wrong with this cloth?

Hi,

Your mesh is non-manifold (as the warning in the first screenshot is telling you). Non-manifold meshes are not supported by Obi. See:
http://obi.virtualmethodstudio.com/tutor...setup.html

"Closed" means that the mesh completely encloses a volume and has no holes in it, like a balloon. This is not an issue, it only means that volume constraints will not be available (because air can't be contained inside the mesh).

Thank you!
