VMT syntax example

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

$decalscale

• In this example the key "$decalscale" is set to a value of "0.1", meaning that the decal is rendered at 1/10th scale inside of the engine. If the source texture for this decal is 128 pixels, it will be 12.8 inches in size in the engine (or about a foot in length).
