NAME
vis
SYNOPSIS
vis [OPTION]... BSPFILE
DESCRIPTION
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.
OPTIONS
-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. Useful for testing.
-level n Select a test level from 1 to 4. Increasing test levels
require more calculations, but compute a tighter PVS.
Finished maps should be compiled with -level 4.
-v Verbose output
-vv Very verbose output
