LightmappedGeneric

LightmappedGeneric It is the shader most commonly used to render brushes, displacements and lightmapped surfaces.

Only some games like support this shader to be used on models.

Todo: Which other games support it?

Supported Parameters

Basics

$basetexture

Defines an albedo texture.

$decal

Use this material as a decal.

$detail

Detail texturing.

$surfaceprop

Links the surface to a set of physical properties.

%tooltexture

Used to blend texture previews in Hammer.

Adjustment

$color

Independently scales the red, green and blue channels of an albedo.

$pointsamplemagfilter (only in )

Disables texture filtering.

$seamless_scale (in all games since )

Mitigation for displacement texture stretching.

Transparency

$alpha

Scales the opacity of an entire material.

$alphatest

Specifies a mask to use to determine binary opacity.

$distancealpha (in all games since )

Vector-like edge filtering.

$nocull

Disables backface culling.

$translucent

Specifies that the material should be partially see-through.

Lighting

$bumpmap

Specifies a texture that will provide three-dimensional lighting information for a material.

$lightwarptexture (in all games since )

Per-texel color modification via a warp texture.

Note:Does not appear to be featured on LightmappedGeneric in CS:GO engine branch.

$selfillum

Determines whether the surface is self-illuminated independent of environment lighting.

$ssbump (in all games since )

Flags the $bumpmap as being a self-shadowing bumpmap.

Reflection

$envmap

Specular reflections.

$phong (only in )

Diffuse reflections.

Note:Phong is reflected only from env_cascade_light.

Todo: Are there reflections from any other light sources?.

Warning:Standard phong color is always white and don't depend on the color of light_environment or env_cascade_light.

Bug:Normal map does not affect phong reflections if there is empty $envmap on the material, or if you haven't assigned any brush face on env_cubemap entity.  [todo tested in ?]

Effect

$nofog

Prevents fog from overdrawing a material.

Caveats

Mapbase

LightmappedGeneric materials in Mapbase should have the shader SDK_LightmappedGeneric.
