Light (map compiling)
From Quake Wiki
What Light Does
Light is a command-line tool, generally named light.exe. You can invoke it from a command prompt, via a shortcut or batch file, or from the "compile" or "build" menus of some level editors.
This is for you if you're struggling finding out how to use the command line tools from tyrutils on linux due to lack of information and guides out there. The only ones I've even read about are focused on the windows GUI version with the three tools in one package. You can find QBSP, Light and Vis already compiled for you in the bin folder.
To find out any of their options, just execute them in the terminal.
"./qsbp" "./vis" "./light"
These will echo out a bunch of options for you to choose from. Works just like the windows version, you convert the .map with QSBP first and then light. You only need Vis for debugging and larger levels so if you're starting out, don't worry about it for now.
Sorry for lack of explanation, I covered it as briefly as I could and it's not at all that difficult.
