Example Code
"EyeRefract"
{
"$Iris" "models/cra0kalo/ct_swat/eye-iris-brown" // Iris color in RGB with cornea noise in A
"$Irisframe" "0" // Frame for the iris texture, 0 being the default frame
"$AmbientOcclTexture" "models/cra0kalo/ct_swat/eye_ao" // Ambient occlusion in RGB, A unused // default texture eyeball_l_ambient
//"$Envmap" "models/cra0kalo/ct_swat/cubemap" // Reflection environment map static
"$Envmap" "models/cra0kalo/ct_swat/eye-reflection-cubemap-" // Reflection environment map
"$CorneaTexture" "models/cra0kalo/ct_swat/eye-cornea" // Special texture that has 2D cornea normal in RG and other data in BA
"$lightwarptexture" "models/cra0kalo/ct_swat/eye_lightwarp" // 1D ramp texture for tinting scalar diffuse term
"$EyeballRadius" "0.5" // Default 0.5
"$AmbientOcclColor" "[0.36 0.25 0.2]" // Default 0.33, 0.33, 0.33
"$Dilation" "0.4" // Default 0.5
"$Glossiness" "1" // Glossiness of eye (1 is default, 0 is not glossy at all)
"$ParallaxStrength" "0.25" // Default 0.25
"$CorneaBumpStrength" "1.25" // Default 1.0
"$halflambert" "1"
"$nodecal" "1"
// These effects are only available in ps.2.0b and later
"$RaytraceSphere" "0" // Default 1 - Enables raytracing in the pixel shader to make the eyeball look round
"$SphereTexkillCombo" "0" // Default 1 - Enables killing pixels that don't ray-intersect the sphere
//Unknown Parameters
"$eyeorigin" "[0 0 0]" // Origin for the eyes
"$irisu" "[0 1 0 0]"
"$irisv" "[0 0 1 0]"
"$Entityorigin" "4.0"
}
