Over at the glBSP page you can download the new version of this nodes builder for OpenGL ports. Some of the significant changes include:
- ported glbsp and glBSPX to MacOS X.
- added new option "-quiet" for less cluttered output.
- glbsp now handles multiple input WADs (GWA mode).
- lumps in the output WAD are now aligned properly.
- automatically removes dummy sectors from BSP tree.
Mmm.. smaller wads. Tastes like victory.
