The Iris properties of the Eye shader. Simulates refraction and pupil dilation using a heightmap. Also has a fake, view-dependent iris scattering effect to simulate multiple material layers.
NOTE: Implicitly affected by the heightmap & iris mask in Eye Textures.
Parameters
| Name | Type | Description |
|---|---|---|
| Tint | Color | Controls the color tint of the iris. |
| Depth | Float [0-0.08] | Depth scale of iris for the fake refraction effect. |
| Pupil Dilation | Float [0-1] | Controls how much the pupil dilates. |
| Shadowing | Float [0.01-X] | Controls how much faked iris lighting is shadowed by the iris at grazing angles. |
| Scatter Intensity | Float [0-X] | Intensity of the fake iris scattering effect. |
| Scatter Power | Float [0.01-X] | Tightness of the fake iris scattering effect. |
