Is there a simple way to detect the external faces of a complex mesh object with internal vertices? I want to remove all hidden vertices and keep all the visible ones. I love poser, I really do. Only problem I have with a project are some hidden internal vertices. Sure pose a figure, add some clothes and hair export to 3D Studio Max and then try to remove all the hidden vertices. The job is Herculean in trying to remove them by hand. Boolean operations sort of help after capping holes. Is there some smart way Max can detect the exterior surfaced and remove the interior mess? I've tried using ClothReyes with it's surface detection ability with little success in making a mold. If anyone can tell me an automated way to remove internal vertices or capture the external ones, please drop me a line. I'd really appreciate it.
