This article is about the shader. For the preceding shader, see Eyes. For the QC property of $model, see Eyeball./ For the tool, see qc_eyes.
EyeRefract It is used to create realistic eyes, which are affected by map lighting and dynamic lighting, such as those from flashlights. This shader is a successor to the Eyes shader from 
Half-Life 2 .
Bug:Although this shader has support for $emissiveblend, it is not fully implemented and does not work properly. [todo tested in ?]Shader Parameters
$iris
$irisframe
$corneatexture
$corneabumpstrength
$parallaxstrength
$dilation
[[$lightwarptexture|$lightwarptexture]]
[[$envmap|$envmap]]
$glossiness
$ambientoccltexture
$ambientocclcolor
[[$ambientocclusion|$ambientocclusion]]
[[$halflambert|$halflambert]]
$raytracesphere
$spheretexkillcombo
$eyeballradius
Other Parameters
$eyeorigin
$irisu
$irisv
$intro
$warpparam
$entityorigin
Todo: Include cloak parameters in here?
Todo: Can this shader be used outside of a model with qc eyes, by using proxies (or in SFM override materials) to modify these shader values?
