Eye Material Inspector reference

You can modify the properties of an Eye material in the Eye Material Inspector.

Refer to Eyes for more information.

Properties

[!include]

Exposed Properties

Sclera

Property	Description
Sclera Texture	Assign a Texture that controls color of the Sclera.
Sclera Smoothness	Sets the smoothness of the Sclera.
Sclera Normal	Assign a Texture that defines the normal map for the Sclera.
Sclera Normal Strength	Modulates the Sclera normal intensity between 0 and 8.
Sclera Diffusion Profile	Sets a Diffusion Profile, controlling the Subsurface Scattering properties of the Sclera.

Iris

Property	Description
Iris Texture	Assign a Texture that controls color of the eye’s Iris.
Iris Clamp Color	Sets the color that will be used if the refraction ray reached the inside of the Cornea
Iris Offset	Sets the offset of the Iris placement, useful since real world eyes are never symmetrical and centered.
Iris Normal	Assign a Texture that defines the normal map for the eye’s Iris.
Iris Normal Strength	Modulates the Iris’ normal intensity between 0 and 8.
Iris Diffusion Profile	Sets a Diffusion Profile, controlling the Subsurface Scattering properties of the Iris.

Pupil

Property	Description
Pupil Radius	Sets the radius of the Pupil in the Iris Map as a percentage.
Pupil Debug Mode	When enabled, displays a debug mode that allows you to calibrate the desired Pupil Radius for your Iris Map. For proper calibration, ensure that the Iris Offset is 0, the Pupil Aperture is 0.5 (the neutral position) and then the white circle must be inside the iris pattern. See the following screenshot for an example:
Pupil Aperture	Sets the state of the pupil’s aperture, 0 being the smallest aperture (Min Pupil Aperture) and 1 the widest aperture (Max Pupil Aperture).
Minimal Pupil Aperture	Sets the minimum pupil aperture value.
Maximal Pupil Aperture	Sets the maximum pupil aperture value.

Limbal Ring

Property	Description
Limbal Ring Size Iris	Sets the relative size of the Limbal Ring in the Iris.
Limbal Ring Size Sclera	Sets the relative size of the Limbal Ring in the Sclera.
Limbal Ring Fade	Sets the fade out strength of the Limbal Ring.
Limbal Ring Intensity	Sets the darkness of the Limbal Ring.

Cornea

Property	Description
Cornea Smoothness	Sets the smoothness of the Cornea.

Geometry

Property	Description
Mesh Scale	The Eye Shader expects a Mesh of size 1 in Object space. If needed, set this parameter to compensate the mesh size. This is independant of the scale on the Transform component.
