Iridescence
Iridescence was merged with Matcap in version 9.0. See: UV Mode: Gradient.
Iridescence is a feature that maps a gradient texture to a mesh using the angle between the viewer and the surface normal. This can create an effect similar to iridescence on a surface, as well as many stylized effects.
Ramp
Type: Color Gradient Texture (sRGB ON)
Ramp texture to be used for the iridescence effect. It's applied as a gradient, from left-to-right, and can be edited using the Thry Gradient Editor by clicking on the gradient display.
This texture can contain alpha to define the opacity of the iridescence effect.
Mask
Type: Data Texture (sRGB OFF)
Mask that defines where to place the iridescence effect. Black will apply no iridescence, while white will apply full iridescence.
Custom Normals
Type: Checkbox
Whether or not a custom normal map should be used for the iridescence effect. This normal map is blended with the normal selected with Normal Select.
Normal Map
Type: Normal Map Texture (sRGB OFF)
Normal Intensity
Type: Float, Range:0.0 - 10.0
When using a custom normal map, this defines how intense the normal map should be.
Normal Select
Type: Dropdown, Options:Pixel/Vertex
Defines which normal to use for the iridescence effect.
Pixel: Use the base normal with all prior normal maps (if any) applied.Vertex: Use the vertex normal with no prior normal maps applied.
Intensity
Type: Float, Range:0.0 - 10.0
How intense the iridescence effect should be. This can cause colors to clamp, so it's recommended to keep the value at or below 1.
Blending
The blending options define how the iridescence effect should be blended with the base color. Generally, only one at a time of these options should be used.
Blend Add
Type: Float, Range:0.0 - 1.0
Adds the iridescence color to the base color. This generally brightens the base color. Black areas will be unaffected, while white areas will brighten. Colors are simply added on top of the base color.
Blend Replace
Type: Float, Range:0.0 - 1.0
Replaces the base color with the iridescence color. At 1.0, the base color is completely replaced with the iridescence color. At 0.0, the base color is completely unaffected. Values in between will blend the base color with the iridescence color.
Blend Multiply
Type: Float, Range:0.0 - 1.0
Multiplies the base color with the iridescence color. This generally darkens the base color. Black areas of the iridescence color will always darken, white areas will not affect the base color, and colored areas will darken if the base color doesn't match the iridescence color in that area.
Emission Strength
Type: Float, Range:0.0 - 20.0
How much emission the iridescence should apply to the final color.
Hue Shift
Type: Checkbox
Enables hue shifting of the iridescence color.
Speed
Type: Float
How much to constantly shift the hue with time. A value of 1 will result in a full hue shift cycle every 20 seconds.
Shift
Type: Float, Range:0.0 - 1.0
How much to shift the base color around the hue circle.
This value is circular, and will have the same result at 0 and 1.
Audio Link
Only visible if Audio Link is enabled.
Scale Band
Type: Dropdown, Options:Bass/Low Mid/High Mid/Treble
Which band to use for the Audiolink scale effect.
Scale Mod
Type: Vector2
How much to add or subtract from the scale (Ramp X Tiling).
