i have a fully finished model that has several edge splits (custom split normals data) so adding a subsuf modifier will create a lot of holes in the mesh.
what is the best way of fixing the subsurf modifier behaviour in an semi automated way?
i tryed removing the doubles and using mark sharp and edge crease on this edges instead but its just too much work. is there a script or something that does that to everything that is affected by remove doubles?
here is a small test object http://www.pasteall.org/blend/42601
