{{otherlang2

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

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.

{{Warning|Cannot be used with <code>$translucent</code> or similar values on [[model]]s. Use [[UnlitGeneric]] shader instead}}


==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> {{note|In Source 2007, use this, NOT $Selfillumtexture.}}


: 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.


;<code>$selfillumtexture <texture></code> 
: Use a selfillum texture.
{{Bug|Deprecated with Source 2007; doesn't work.}}

;<code>$selfIllumFresnel<[[bool]]></code>
:Allows the material to use Fresnel ranges. {{Todo|Confirm}}

;<code>$selfIllumFresnelMinMaxExp [n n n]</code> 
:Default: 0.0 1.0 1.0.  Like the phong Fresnel ranges, but with selfillum.
