$translucent

The $translucent VMT command Specifies that the material should use the alpha channel of the $basetexture.VTF to mask transparent sections of the material.

VMT syntax example

"LightmappedGeneric"
{
    "$basetexture" "decals/mydecal"
    "$decal" 1
    "$decalscale" 0.10
    "$translucent" 1
}

• Used with UnlitGeneric, VertexLitGeneric, LightmappedGeneric and many more shaders.

• Warning: There are reports of a Rendering bug which reverses the overlay order of multiple translucent materials; so that the further material occludes the nearer one. The preferred solution appears to be to use $alphatest instead or $translucent.

Additional Parameters

$additive

"$additive" 1

• Renders the texture additively (Its colors are added to, instead of replacing, what is displayed behind it).

$alpha

"$alpha" <float>

• Scales material opacity by the 'float' number.
• Every pixel with an alpha value less than 178 will be completely transparent in game. However, values close to this value will confuse the shader at distances.(see $alphatest)
