VVIS

VVIS is the command-line tool that takes a compiled BSP map and embeds visibility data into it. VVIS tests which visleaves can see each other, and which cannot. See Visibility optimization for a more detailed explanation.

VVIS will:

• Test visibility between visleaves by clipping their view planes.
• Enforce a maximum visibility distance, if configured to.

Syntax

vvis [options...] <bsp file>

For example:

"%sourcesdk%\bin\orangebox\bin\vvis" -tmpout sdk_trainstation_01

This will generate and embed a visibility chart, writing portal data out to .\tmp\sdk_trainstation_01.prt.

Options

Use these in combination with expert compile mode or a batch file:

Functions

-fast

Only do a quick first pass. Does not actually test visibility.

-radius_override <int>

Force a maximum vis radius, in units, regardless of whether an env_fog_controller specifies one.

-nosort

Don't sort (an optimization) portals.

-tmpin

Read portals from \tmp\<mapname>.

-tmpout

Write portals to \tmp\<mapname>.

General

-low

Run as an idle-priority process.

-threads

Control the number of threads used. Defaults to the # of processors (times 2 for Hypertreading/SMT CPU's) on your machine.

-v

-verbose

Turn on verbose output

-novconfig

Don't bring up graphical UI on vproject errors.

-mpi

Use VMPI to distribute computations.

-mpi_pw <string>

Use a password to choose a specific set of VMPI workers.

-vproject <string>

-game <string>

Override the VPROJECT environment variable.
