Today, I gained a sudden interest in map editing for Nexuiz. I've never really done anything regarding map-editing/making in quake-based games ever, unless you count creating random things under Sketchup or Gmax. I was wondering what tools would be appropriate for editing and creating maps in Nexuiz (other than GTKRadiant) as well as any guides that may be deemed as useful.

somewhere here in the Forum is some Thread called "Mapping tutorials" or somethin like this.

If i remember right u will find everythin u need there.

I took a look, the thread u should look in is right over this one here atm.

U should take a look at this here too :

Im not sure, but if u have Gmax setup properly, it should work. You may have to add entities with GTKRadiant. If you have a copy of Milkshape, it also has a couple tools bundled with it.
