Enhance:AM SpecialFX Series
AM_Irid Texture
This texture applies iridescent pattern to the object as though there is a thin film on it. The apparent thickness of the film can be controlled along the proportional wavelengths of each color component.
Function Parameters
Red Green Blue Wavelengths These parameters determine the proportional wavelength of each color component as dispersed by the iridescent thin film.
Function Thickness This parameter sets thickness of the iridescent film. The larger this value the more dispersed the color spread will be.
Function Boost This parameter controls the amount of iridescence that is applied. At 100% it is applied full on and at 0% the object's color will be unmodified.
Function Edge Fade When this check box is checked the application of the Irid color is faded at the edges for the object where the angle between the camera and the surface approaches 90 degrees.
Function Reverse Then this check box is checked the irid function is applied from 0 to 90 degrees otherwise it is reversed and applied from 90 to 0 degrees. The degrees refer to the angle between the object and the camera. Zero degrees is face-on and 90 degrees is side-on.
Wave Type This control allows one of seven different function wave types to be used. By passing the texture function through a waveform generator different shader patterns can be created. These are shown below:

Axis Parameters
Scale These three parameters control the size of the texture in the X, Y and Z direction respectively. The textures are applied to an object based on a texture axes where the size of the axes controls the size of the texture. These parameters therefore control the scale of the texture axes and therefore the size of the texture.
Center These three parameters control the center of the texture with respect to an object's center point. The textures are applied to an object based on a texture axis the center of the texture axis is by default at the center point for the object. The center texture axis can be moved away from the center point by adjusting these parameters. These three parameters control the translation of the center of the texture in the X, Y and Z axis respectively.
Rotate These three parameters control the orientation of the texture with respect to the object. The textures are applied to an object based on a texture axis that is by default lined up to the X, Y and Z axis of the object. The texture can then be rotated with respect to the object about the texture axes center using these three parameters.
Axis This parameter sets the direction along which, or around which, the texture pattern will be applied.
Color Map
Opacity This parameter controls the opacity of the irid.
Reverse Affects When this check box is enabled the affect used for controlling the other object attributes is reversed. This means that you could have glowing edges or a glowing center.
Affect Others
Diffuse Falloff The alpha map, created by the alpha values, the blend points and the texture function can control the Diffuse Falloff on the object. This parameter controls the maximum possible Diffuse Falloff. This means that the range will be between 0% and the Diffuse Falloff setting modulated by the Alpha Map. A switch is provided that determines whether the alpha map is used to affect the Diffuse Falloff. For information about Alpha Maps Click Me.
Ambience As with the Diffuse Falloff the Ambience of the object can be controlled by the current alpha map.
Reflectivity As with the Diffuse Falloff the Reflectivity of the object can be controlled by the current alpha map.
Reflectivity Falloff As with the Diffuse Falloff the Reflectivity Falloff of the object can be controlled by the current alpha map.
Roughness As with the Diffuse Falloff the Roughness of the object can be controlled by the current alpha map.
Roughness Scale As with the Diffuse Falloff the Roughness Scale of the object can be controlled by the current alpha map.
Radiance As with the Diffuse Falloff the Radiance of the object can be controlled by the current alpha map.
Affect Specularity
Specular Color This is the color will be used for the specular color unless the Use Derived Color is switched ON.
Affect Specular Color When this switch is ON the color of the specular highlight will be affected by the texture assuming an alpha map has been set up.
Use Derived Color If the Use Derived Color is OFF then the preset Specular Color, as above, is used otherwise if it is ON then the color result from the actual texture is used.
Specular Size The alpha map, created by the alpha values, the blend points and the texture function can control the Specular Size on the object. This parameter controls the maximum possible Specular Size. This means that the range will be between 0% and the Specular Size setting modulated by the Alpha Map. A switch is provided which determines whether the alpha map is used to affect the Specular Intensity. For information about Alpha Maps Click Me.
Specular Intensity As with the Specular Size the Specular Intensity of the object can be controlled by the current alpha map.
Affect Transparency
Transparency The alpha map, created by the alpha values, the blend points and the texture function can control the transparency of the object. This parameter controls the maximum possible transparency. This means that the range will be between 0% and the transparency setting modulated by the Alpha Map. A switch is provided which determines whether the alpha map is used to affect the transparency. For information about Alpha Maps Click Me.
Density As with the Transparency the Density of the object can be controlled by the current alpha map.
Refraction As with the Transparency the Refraction of the object can be controlled by the current alpha map.
Translucency As with the Transparency the Translucency of the object can be controlled by the current alpha map.
