$selfillum: Difference between revisions

Revision as of 15:13, 5 April 2008

The $selfillum VMT command uses the alpha channel of the $basetexture to set minumum clamps on the lighting, making it seem like the material glows in the dark.

Alternatively, for Dx9 only, see $selfillum_envmapmask_alpha to use the alpha channel of the $envmapmask VTF for the luminosity map.

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

For the texture's alpha channel, a value of 255 means 100% self-illumination, while an alpha value of 0 means 0% self-illumination.

The $selfillumtint VMT command is used to adjust the color of $selfillum.

"$selfillumtint"
