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

[[Category:Shader parameters|s]]
The effect is masked by default by the [[alpha channel]] of <code>[[$basetexture]]</code>, but there are other options (see below). Wherever the mask is located, 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==
 
; <code>$selfillumtint "[<red [[float]]> <green float> <blue float>]"</code>
: Adjusts the colour of the self-illumination effect. Default value is "[1 1 1]".
;<code>$selfillummask <texture></code>
: A dedicated mask texture for the effect. Might not work in Ep1.
; <code>$selfillum_envmapmask_alpha <[[bool]]></code>
: Has the material derive its self-illumination mask from the alpha channel of the <code>[[$envmapmask]]</code>. Requires DirectX 9.
