Digital Human Eye settings

Left / Right Eye: Use these two radio buttons to select and display one of the eye settings below.

• Common
  
  1. SSS Color: Determines the color of the light that passes through the eyeballs.
  2. IOR: Adjusts the slider to define how much light bends when passing through the cornea and aqueous humor. The higher the value, the more the light bends.
     

     IOR = 1.000	IOR = 5.000

  3. SSS Strength: This value controls the visibility of the SSS color applied to the eyes.
  4. Specular Scale: Adjust this value to determine the size of the specularity on the eye, the higher the value, the larger the specular highlights appear on the skin.
     

     Specular Scale = 0.000	Specular Scale = 1.000

• Iris
  1. Iris Color: This setting blends a color onto the iris Base Color map.
     Before and after changing the color of the iris color to green.
  2. Iris Cloudy Color: Uses the color swatch to determine the color of the aqueous humor.
     Before and after changing the color of the aqueous humor color to purple.
  3. Iris Inner Color: Uses the color swatch to determine the color of the inner part of the iris.
     Before and after changing the color of the inner iris color to dark green.
  4. Iris Roughness: Use this slider to set the smoothness of the corneas.
     

     Iris Roughness = -1.500	Iris Roughness = 1.500

  5. Iris Color Brightness: Use the slider to set the lightness of the iris.
     

     Iris Color Brightness = 1.950	Iris Color Brightness = 5.000

  6. Pupil Scale: Adjusts the size of the pupil.
     

     Pupil Scale = 0.970	Pupil Scale = 0.910

  7. Iris Inner Scale: Adjust this slider to change the size of the inner iris.
     

     Iris Inner Scale = 0.100	Iris Inner Scale = 0.150

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

     Iris UV Radius = 1.000	Iris UV Radius = 0.078

• Limbus
  1. Limbus UV Width Color: This value controls the sample size for the limbus, or how much of the eye surface will be allowed for showing the limbus.
     

     Limbus UV Width Color = 0.000	Limbus UV Width Color = 0.350

  2. Limbus Dark Scale: Use this slider to control the size of the darkness around the limbus.
     

     Limbus Dark Scale = 7.042	Limbus Dark Scale = 0.000

• Sclera
  1. Sclera Bloodshot Color: Use the color swatch to determine the color of the bloodshot on the eye.
  2. Sclera Bloodshot Strength: Determines the intensity of the bloodshot in the eyes.
     

     Sclera Bloodshot Strength = 0.400	Sclera Bloodshot Strength = 0.990

  3. Sclera Bloodshot Range: Determines the range of the bloodshot coverage. Higher values equate to broader coverage.
     

     Sclera Bloodshot Range = 0.500	Sclera Bloodshot Range = 0.000

  4. Sclera Normal Strength: Sets the bumpiness of the sclera.
     

     Sclera Normal Strength = 1.000	Sclera Normal Strength = 1.980

  5. Sclera Flatten Normal: Sets the level of protrusion and concavity of the fine lines within the sclera region.
     

     Sclera Flatten Normal = 1.200	Sclera Flatten Normal = -5.000

  6. Sclera Normal UV Scale: Change the value to define how much light bends when passing through the cornea and aqueous humor. The higher the value, the more the light bends.
     

     Sclera Normal UV Scale = 5.000	Sclera Normal UV Scale = 0.000

  7. Sclera Roughness: Use the slider to control the smoothness and reflection on the sclera.
     

     Sclera Roughness = 0.045	Sclera Roughness = -1.500

  8. Sclera Brightness: Change the value to determine the brightness of the eye whites.
     

     Sclera Brightness = 1.600	Sclera Brightness = 5.000

  9. Sclera UV Radius: Adjust the value to define the amount of tiling for the entire eye texture (iris excluded).
     

     Sclera UV Radius = 1.000	Sclera UV Radius = 0.580
