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

$parallaxmap is a material shader parameter available in all Source games. It specifies the VTF texture to use for the 'sub-vertex modeling' or parallaxmap of the material surface. The texture used for this parameter is a Heightmap.

Warning:Parallax maps are disabled in every Valve game, although since an (unfinished) shader exists named ParallaxTest, which can be used as an alternative.

VMT Syntax

"$parallaxmap" <texture path>
"$parallaxmapscale" <float> // Scales the $parallaxmap Y value by this amount
