The Demoman's eyeball, using the EyeRefract shader.
This article is about the QC property of $model. For the shaders used to render the eyes, see EyeRefract and Eyes. For the tool, see qc_eyes.
Eyeball is a property of $model. It defines the data needed to properly render a character's eyes, defining the name, positioning, size and material of the eyeball.
Parameters
Tip:The qc_eyes tool can help you manage the potentially confusing string of numbers needed for this command.<name>- Name of eyeball, used to match eyelid rules. For humans, use
righteyeandlefteye. <bone_name>- The bone which the eye is parented to, typically the head.
<X> <Y> <Z>- World location of the center of the ball of the eye. While your eye doesn't need to be a sphere in the model, Source will always map the material according to an invisible ball.
<material_name>- Material of the eye. Make sure each or every eye has a unique one. It is recommended to use a material using the
EyeRefractshader. <diameter>- Width of the eyeball when viewed from the front. Used to prevent the iris from rolling inside the head.
Note:Doesnt seem to take any effect since the Y axis of the eyes overrides this feature Todo: Further testing <angle>- Default yaw offset (from directly forward) for the iris. Humans are typically 2-4 degrees wall-eyed. Not setting this correctly will result in either your characters appearing cross-eyed, or if you've compensated by misplacing the ball of the eye, them not tracking side to side. Should be a negative value for the left eye, and a positive value for the right eye.
<iris_material>- Material used as the iris texture. (This property is deprecated)
<iris_scale>- Scale of the iris texture. The model's UV map does not influence the eye material in any way. Todo: While this is true for
EyeRefract, is this also true for theEyesshader?
Example
Hover your mouse over each value for its description.
$model female_01 "female_01_reference_RE" { eyeball righteye ValveBiped.Bip01_Head1 -1.261 -3.702 64.974 eyeball_r 1 4 pupil_r 0.66 }
