Original tyurtils:

Build Status Build status


ericw-tools is a branch of Tyrann's quake 1 tools, focused on adding lighting features, mostly borrowed from q3map2. There are a few bugfixes for qbsp as well. Original readme follows:

A collection of command line utilities for building Quake levels and working with various Quake file formats. I need to work on the documentation a bit more, but below are some brief descriptions of the tools.

Included utilities:

  • qbsp - Used for turning a .map file into a playable .bsp file.

  • light - Used for lighting a level after the bsp stage. This util was previously known as TyrLite

  • vis - Creates the potentially visible set (PVS) for a bsp.

  • bspinfo - Print stats about the data contained in a bsp file.

  • bsputil - Simple tool for manipulation of bsp file data

See the doc/ directory for more detailed descriptions of the various tools capabilities. See for a brief overview of recent changes or for the full changelog and source code.


Requires CMake 2.8, groff, and a compiler with C99 and C++11 support.
