What is the name of a polygon that ends to the void?
I mean that an object with incomplete faces and the edge that borders no other polygons. For example, a poly plane primitive.
I ask this as I have brought a sword into zBrush and I separated a small section of faces that were modelled as a faceted gemstone. I chopped the object into separate subtools and wanted to start defining the hard corners using the crease tool. The creasing seemed to be going ok but the edge that has no connecting polygons still seems to be buckling in on itself. I can only assume it is because of that edge.
So i am after a noun for a polygon type so I can then do a search on the zBrush creasing documentation to determine if the border edge is screwing me or my model has some funky non manifold geo.
