$selfillum

The $selfillum VMT command makes a material glow in the dark. Shaders commonly support this effect.

The effect is masked either by the alpha channel of $basetexture or with a greyscale texture specified with $selfillummask. In either case, white areas are self-illuminated while black areas are not.

VMT syntax example

$selfillum <bool>

LightmappedGeneric
{
    $basetexture props/tvscreen005a
    $selfillum 1
    $surfaceprop glass
}

Additional parameters

$selfillumtint <RGB matrix>

Adjusts the colour of the self-illumination effect. Default value is "[1 1 1]".

$selfillummask <texture>

A dedicated masking texture for the effect. If this command is not used, the alpha channel of $basetexture will be used instead. Might not work in Ep1.

$selfillum_envmapmask_alpha <bool>

Has the material derive its self-illumination mask from the alpha channel of the $envmapmask. Requires DirectX 9.
