vis − Compute visibility (PVS) for a Quake BSP file
vis [OPTION]... BSPFILE
vis is a tool used in the creation of maps for the game Quake. vis looks for a .prt file by stripping the file extension from BSPFILE (if any) and appending ".prt". vis then calculates the potentially visible set (PVS) information before updating the .bsp file, overwriting any existing PVS data.
This vis tool supports the PRT2 format for Quake maps with detail brushes. See the qbsp documentation for details.
Compiling a map (without the -fast parameter) can take a long time, even days or weeks in extreme cases. Vis will attempt to write a state file every five minutes so that progress will not be lost in case the computer needs to be rebooted or an unexpected power outage occurs.
−threads n
Set number of threads explicitly. By default vis will attempt to detect the number of CPUs/cores available.
|
−fast |
Skip detailed calculations and calculate a very loose set of PVS data. Sometimes useful for a quick test while developing a map. |
−level n
Select a test level from 0 to 4 for detailed visibility calculations. Lower levels are not necessarily faster in in all cases. It is not recommended that you change the default level unless you are experiencing problems. Default 4.

−v |
Verbose output. |

−vv |
Very verbose output. |
