Supported Parameters

$bumpmap

Normal mapping.

$color2

Color tinting.

$decaltexture (only in )

Use a 2nd UV channel for high-resolution decal support.

$detail

Detail texturing.

$envmap

Specular reflections.

$emissiveblend (in all games since )

Advanced flowing self-illumination, used on the Vortigaunts in Half-Life 2: Episode Two.

$flesh (in all games since )

The flesh effect used for Alyx in Half-Life 2: Episode Two.

$halflambert

Half-lambertian shading.

$lightwarptexture (in all games since )

Per-texel color modification via a warp texture.

$phong (in all games since )

Diffuse reflections.

$rimlight (in all games since )

Constant rimlight based on phong and the ambient lighting.

$selfillum

$translucent

$alpha

Expensive and cheap transparency.

$compress (in all games since )

$stretch (in all games since )

Wrinklemaps for character faces.

$treeSway (in all games since )

Vertex manipulation to give the effect of trees swaying in the wind.

Misc Parameters

$flashlightnolambert <boolean> (in all games since )

Tell projected textures such as the flashlight to ignore the surface normal of the model. Useful for models with $nocull such as foilage. Otherwise, lighting the face with a flashlight from behind will not affect it. Default 0.

$seperatedetailuvs <boolean> (in all games since )

To do: Use texcoord1 for detail texture

$desaturatewithbasealpha <float> (in all games since )

Use the base alpha to desaturate the base texture. Set to non-zero to enable, value gets multiplied into the alpha channel before desaturating.

$lowqualityflashlightshadows <boolean> (in all games since )

Force low quality flashlight/projected texture shadows for faster performance.

$allowfencerenderstatehack <boolean> (in all games since )

Fence render hack for cascade shadow maps, allows shadow maps to work properly with fences.

$disablecsmlookup <boolean> (in all games since )

Disable cascade shadow map lookup/filtering, useful on dense foilage.

$allowdiffusemodulation <boolean> (in all games since )

Prevents the model's material from being tinted by $color2 or rendercolor.

$notint <boolean> (only in )  (also in )

Prevents the model's material from being tinted by $color2 or rendercolor.

Cloak

VertexLitGeneric natively supports the Spy cloak effect from Team Fortress 2. You will want to combine it with a sine wave proxy for the full effect.

$cloakpassenabled <boolean>

Enables cloaking effects.

$cloakfactor <normal>

0 = fully visible, 1 = fully invisible.

$cloakcolortint <RGB matrix>

Colors the refraction effect. Default is white.

$refractamount <float>

How strong the refraction effect should be when the material is partially cloaked. Default 2.
