Self-illumination

Self-illumination on the Cheater's Lament.

See the VDC on $selfillum for how this is implemented in materials.

Self-illumination is a feature of the Source Engine that causes certain textures to appear to glow when in areas with little light. This effect is used to add to the appearance of certain items in Team Fortress 2.
