Parameters
Basics
$basetexture <texture>
Default: shadertest/BaseTexture
Description: Base texture with lighting built in.
$basetexture2 <texture>
Default: shadertest/lightmappedtexture
Description: Blended texture for use with displacements
Appearance
$basetexturetransform <matrix>
Default: center .5 .5 scale 1 1 rotate 0 translate 0 0
Description: Base Texture Texcoord Transform. Transforms the texture before use. Does not affect lightmaps.
$color <color>
Default: [1 1 1]
Description: Adjusts the color of $basetexture
$color2 <color>
Default: [1 1 1]
Description: Adjusts the color of $basetexture2
$frame <int>
Default: 0
Description: Sets what static frame to use if $basetexture is animated
$frame2 <int>
Default: 0
Description: Sets what static frame to use if $basetexture2 is animated
$srgbtint <color>
Default: [1 1 1]
Description: Tint value to be applied when running on new-style srgb parts
$hsv <color>
Default: [1 1 1]
Description: HSV color to transform $basetexture texture with
$hsv_blend <bool>
Default: 0
Description: Blend untransformed color and HSV transformed color
Flashlight
$flashlighttexture <texture>
Default: effects/flashlight001
Description: Flashlight spotlight shape texture

Default: 0
Description: Sets what static frame to use if $flashlighttexture is animated
Physically Based Rendering
$model <bool>
Default: ``
Description: Specifies if the material is intended for use on models or brushes. If set to 1, acts like VLG (phong for lights, no lightmaps). If set to 0, acts like LMG.
$mraotexture <texture>
Default: ``
Description: Texture with metalness in R, roughness in G, ambient occlusion in B for $basetexture
$mraoframe <int>
Default: ``
Description: Sets what static frame to use if $mraotexture is animated.
$mraotexture2 <texture>
Default: ``
Description: Texture with metalness in R, roughness in G, ambient occlusion in B for $basetexture2
$mraoframe2 <int>
Default: ``
Description: Sets what static frame to use if $mraotexture2 is animated.
$mraoscale <color>
Default: [1 1 1]
Description: Factors for metalness, roughness, and ambient occlusion for $mraotexture
$mraoscale2 <color>
Default: [1 1 1]
Description: Factors for metalness, roughness, and ambient occlusion for $mraotexture2
$parallax <bool>
Default: 0
Description: Enables Parallax Occlusion Mapping.
$parallaxdepth <float>
Default: 0.0030
Description: Depth of the Parallax Map. Essentially the intensity of the heightmap.
$parallaxcenter <float>
Default: 0.5
Description: Center depth of the Parallax Map. Essentially how far away from the face the center of the heightmapped material appears to be.
$blendtintbymraoalpha <bool>
Default: 0
Description: Blend tint by the alpha channel in MRAO texture. Similar to $blendtintbybasealpha for VLG
Alpha
$alpha <float>
Default: 1.0
Description: Scales the transparency of the whole image
$alphatestreference <float>
Default: 0
Description: Specifies the threshold alpha channel value at which the surface should be transparent instead of opaque. A value of “.3” will create a thicker shape while a value of “.7” will create a thinner shape.
Emissive
$emissiontexture <texture>
Default: ``
Description: Emission texture
$emissionframe <int>
Default: ``
Description: Static frame to use if $emissiontexture is animated.
$emissiontexture2 <texture>
Default: ``
Description: Emission texture for $basetexture2
$emissionframe2 <int>
Default: ``
Description: Static frame to use if $emissiontexture2 is animated.
$emissionscale <color>
Default: [1 1 1]
Description: Color to multiply $emissiontexture with
$emissionscale2 <color>
Default: [1 1 1]
Description: Color to multiply $emissiontexture2 with
Reflection

Default: paint/splatnormal_default
Description: The paint splat normal map to use when paint is enabled on the surface
$paintsplatbubblelayout <texture>
Default: paint/bubblelayout
