q3map2 can now also create minimaps, for an easier workflow. It's even in the build menu of current NetRadiant builds.
These minimaps however totally ignore patches. If it's good enough for you, you now have a much simpler workflow to make minimaps for your map.
Note that it writes _mini.tga maps and not _radar.tga maps. This is no problem, as Nexuiz supports both, but you cannot rename it to _radar.
So basically, _mini is no longer deprecated - q3map2 has no box tracing function, and is thus unable to make _radar maps. This info might be important for people making map packaging scripts.
