$surfaceprop

Stub

This article or section is a stub. You can help by expanding it.

The $surfaceprop command is used to apply a set of physic-interaction attributes to a Model (as a QC command) or a Brush Material (as a VMT command).

• The basic principle is the same in both cases; the $surfaceprop may affect :

• the object's density for physics calculations such as $automass,
• what sounds it makes when it collides,
• what particles it emits when shot,
• what decals it acquires when shot, etc
• what gibs it throws up if it breaks.

• HLMV can be used to generate blocks of .QC file that sets the surface properties correctly.
• If no $surfaceprop is defined, the "default" surfaceprop (which is something like concrete) is used.
• See also $jointsurfaceprop.

Example Syntax

$surfaceprop "<surfaceproperty_name>"

where

<surfaceproperty_name>

is a brush surface property defined in the /scripts/surfaceproperties.txt file (see Material Surface Property),

or a model surface property defined in the /scripts/surfaceproperties_hl2.txt file.
