I'm actually working on one right now ;D
I'm Wintahs from the Gearbox forum, the one with the crashing editor. You posted in my thread a couple of days ago.
The problem still isn't solved, so I'm gonna start over as soon as my first UT3 map is done, wich from the looks of it wouldn't take very long.
And thanks for writing those tutorials, they've been very helpful.
