You are indeed correct, using the mapconvert script stickied on the forums worked just fine. What didn't was converting Brewell's maps. Those came throuogh without any lines and the existing .map files I have are a mess. Weird! If you need any help testing maps, let me know. In the meantime, I'll use the lame ones I converted from everquest/maps folder and test other SEQ functionality.
So far the convert to qt4 is looking great! Nice job
