Bumpmapping.

$color2

Color tinting.

$detail

Detail texturing.

$envmap

Specular reflections.

$emissiveblend

Advanced flowing self-illumination, used on the Vortigaunts in Episode 2.

$flesh

$flashlightnolambert <bool>

To do: Flashlight pass sets N.L=1.0

$seperatedetailuvs <bool>

To do: Use texcoord1 for detail texture
