Making maps for Unvanquished requires some external tools. They are all free.
Optional Mapping Tools
It is recommended you start with NetRadiant, however many other options are available:
|Program||Tested||Recommended||Mapping method||Supported OSes||Last stable release||Notes|
|Mac OS X||Windows||Linux|
|Yes||Yes||Brushes||10.5 & 10.6||Yes||Yes||Current (2015)||Highly recommended brush-based editor. Mac users need X11 (10.7 users can get this from the XQuartz project). Arch Linux users can use the netradiant-git PKGBUILD in the AUR.|
|GtkRadiant||Yes||Brushes||Yes||Yes||Yes (source)||1.6.6 (2018)||Predecessor of NetRadiant. Brush based.|
|Blender||Yes||Polygons||Yes||Yes||Yes||Current||Extremely popular and open-source polygon based modelling tool. See the katsbits tutorial for getting it to work with Unvanquished.|
|MacRadiant||Brushes||Yes (Intel & PPC)||Unknown (v1.4 and v1.5)||Problems have been reported with Snow Leopard and Leopard, though there are workarounds. See the download page for more information.|
|QuArK||Brushes||Current (2013)||An all in one quake editor, capable of much more than mapping.|
|TrenchBroom||Brushes||10.6 or newer||Yes||Yes||Current (2017)||Editor for quake 1 maps, possibly with quake 3 mapping support. Notably not a Radiant derivative|
|DarkRadiant||Brushes||Yes (source)||Yes (32 and 64-bit)||Yes (Debian/Ubuntu and source)||Current (2017)||Designed for a Doom 3 mod. Quake 3 map format (used by Unvanquished) is not yet complete.|
|J.A.C.K||Brushes||Yes (32-bit)||Yes (32 and 64-bit)||Current (2016)||Designed for Half-Life and some id Tech engines, the map format is different (map220) and needs a modified q3map2 to be compiled. Notably not a Radiant derivative.|
|Milkshape 3D||Brushes||Yes (32-bit)||Abandoned (2011)||Designed originally for Half Life|
|Gmax||Polygons||Yes||Abandoned (2005)||Freeware version of polygon-based modelling tool 3DsMax. Used by many games but never updated: small bugs exist. May require a registration bypass to work (easily found) as the registration web-form has disappeared.|
Brush based editors require you to make your maps using constructive solid geometry (CSG). Most mapping tutorials for Quake-like games such as Unvanquished follow this method.
Polygon based editors give a larger focus on 2D shapes making up 3D ones, which can be more powerful but is more difficult to teach and learn. These editors generally support 'boolean operations', allowing them to be used like CSG editors, but with more difficulty.
