NodrawDon't say you are going to nodraw everything at the end. If I were you, I would create everything with nodraw, then if I actually want to test the map, I would texture it. It doesn't take longer than 1 minute to do this process (At least what I've seen so far). Select everything, apply nodraw on everything and apply textures on the faces. I'm going to say this once again, the map file size will be pretty god damn high, even with Fast-DL. For the sake of your map and the download speed, I'm not even going to request a room, lol.
And It's time for you to stop using box-technique for sealing your map. I hope I see these modifications in the release version.
