Here is where you find
other great sites.
The following are good sites for quake 3, not just mapping, but for news
in general and lots of other stuff for Quake III: Arena.
These are some of the programs that I
have found useful, if you want to find them or something like them,
(because things change so much) the best place to start looking would be
PlanetQuake or PolyCount.
Tools, GTK Radiant - Must have for mapping
Java MD3 Model Viewer - This is a great program to view stuff in your
Pop N Fresh's 3D
Studio Max Plugins - These will allow you to import and export MD3
MD3 Compiler - Good program for importing and exporting files.
3D Studio Max - In my opinion this is the best 3D
modeling program out there.
WinZip - Use this
to extract the files from within your PK3 files.
EditPad - Great
replacement for Notepad has more advanced features to work with SHADERS
