Someone or some people created a *beautiful* episode 1 map of Naboo complete with the working force fields and pit section where Qui Gon met his noble end. It was done for Unreal Tournament. How hard would it be to convert that kind of map over to Q3 - or can you not convert that kind of map?
It would be too bad if you couldn't since the map (there are some others - Mos Eisley, Death Star, Star Destroyer) is absolutely stunning in it's attention to detail. Hell, I kept getting slaughtered because I was too distracted by the scenery... "Hey look! They even have the Queen's ship in the bay!!" BAM!! Smoked.
