What I was doing was doing basic stuff in gtk and importing maps and exporting them into .3ds with this

That's why I said brushes. Less brushes in the end product will mean less polys.
Also I wasn't going to release the FULL map in the beta tests. Why would anyone steal my unfinished map with a ton of holes in it? They'd need to finish it. Even if they did that it wouldn't be the Original.
