The complete source code for LuxRender is available from our Mercurial Repository:
http://src.luxrender.net/lux
The source for the exporters and other parts of the LuxRender project are also in Mercurial, and are listed here:
http://src.luxrender.net/
At times, cloning the repository from our main server may fail due to limited resources. We also have a mirror of the repositories available on bitbucket.org which should be a lot faster and more reliable:
http://bitbucket.org/luxrender
In case you want to compile LuxRender yourself, please check the Building_on_Windows, Building_on_OSX or Building_on_Linux wiki pages.
