My friend wants to maybe map for Nexuiz on windows.
We tried along time ago using the old radiant and stuff and it kinda worked but was involved to get working. Now the new radiants come with Nexuiz support built in I hear. How do I get it to work with Nexuiz 2.3 on windows. I need instructions for newer radiant (1.5x).

Just loaded up radiant 1.5 to check the settings and IT WONT START!
I'll reinstall later and give you a step-by-step.

I have it running on a couple of machines (so I can mess with my latest map from wherever I'm at in the house), using the latest GtkRadiant 1.5 installed to default lcation in C drive, and Nexuiz placed in C:\Program Files\Nexuiz. I put Nexuiz in first (not sure if that even matters). I gave it the path to the Nexuiz engine, where I installed Nexuiz. It just works, I haven't had a problem... I'm using XP, are you XP or Vista?
