$rimlight

Example of rim lighting in use on the TF2 Heavy.

The $rimlightVMT command adds a rim light to the model that appears to come indirectly from the environment. The color of the rim light is directly influenced by Ambient light.

Note:Template:EP2 add Requires $phong to be set to 1. Phong shading is only available with VertexLitGeneric.

Todo: Explain similarities and differences of Phong Fresnel ranges.

VMT syntax

$rimlight <bool>

 VertexLitGeneric
{
	$phong			1

	$bumpmap		<texture>
	$phongexponent		5		// either/or
	$phongexponenttexture	<texture>	// either/or
	$phongboost		1.0
	$phongfresnelranges	"[0 0.5 1]"

	$rimlight               1
	$rimlightexponent       2
	$rimlightboost          .2			
}

Additional parameters

$rimexponent <int> Template:EP2 add

Exponent for phong component of rim lighting. The rim exponent defines the "tightness" of the highlight. A higher exponent results in a smaller, tighter highlight while a lower exponent results in a broader flatter one.

$rimboost <int> Template:EP2 add

Boost for ambient cube component of rim lighting.

$rimmask <texture> Template:EP2 add

Todo: Needs documentation.
