 "$Envmap"             "models/cra0kalo/ct_gign/eye-reflection-cubemap-"    // Reflection environment map
 "$CorneaTexture"      "models/cra0kalo/ct_gign/eye-cornea"                 // Special texture that has 2D cornea normal in RG and other data in BA

 "$EyeballRadius" "0.5"    // Default 0.5

 "$Dilation" "0.5"     // Default 0.5
 "$ParallaxStrength" "0.25"          // Default 0.25
 "$CorneaBumpStrength" "1.25"   // Default 1.0

 "$halflambert" "1"
