Iris

The Iris sub-section can be used to adjust the iris and the aqueous humor(the liquid between the cornea and the lens).

Basic Settings

• Iris Depth Scale: This value determines the depth of the iris.

  Iris Depth Scale = 1.3000	Iris Depth Scale = 2.000

• Iris Roughness: You can use this slider to set the smoothness of the corneas.

  Iris Roughness = 0.000	Iris Roughness = 0.400

• Iris Color Brightness: You can use this value to set the lightness of the iris.

  Iris Color Brightness = 0.600	Iris Color Brightness = 1.500

• Pupil Scale: This value can be used to set the size of the pupil.

  Pupil Scale = 0.960	Pupil Scale = 1.500

Advanced Settings

• IOR: This value defines how much light bends when passing through the cornea and aqueous humor. The higher the value, the more the light bends.

  IOR = 1.400 (water)	IOR = 5.000

• Iris Cloudy Color: You can use the color swatch to determine the color of the aqueous humor.

  Iris Cloudy Color = #000000	Iris Cloudy Color = #000022

• Iris Inner Color and Iris Inner Scale: You can use these two sliders to determine the masked color and size to overlay on the original iris texture.

  Iris Inner Color = #FFDF7D (light yellow) Iris Inner Scale = 0.000	Iris Inner Color = #55FF00 Iris Inner Scale = 1.000

• Iris UV Radius: This setting determines the size of the iris and cornea.

  Iris UV Radius = 0.156	Iris UV Radius = 0.100

• Iris Color: This setting blends a color onto the iris color on the Base Color channel in the Texture Section.

  Iris Color = #FFFFFF (keep the base color texture)	Iris Color = #005500 (dark green)
