that base mesh looks like its over 2000 faces, am i right? umm, if you already pressed convert try pressing 3, if it doesnt smooth, than just raise the maximum number of faces to over 5000 or something, then it should work.... but i need to worn you, if you add that tool to the shelf, you cant change the settings, it alays goes back to 100 or w/e



i hope that helps ^_^
