The plugin can be used as a reflection color map in a material with the Fresnel option of the material turned off (this plugin does its own Fresnel calculations).
Min – the minimum thickness of the thin film, in nanometers.
Max – the maximum thickness of the thin film, in nanometers.
Map – a texture map that specifies the actual thickness of the film between the specified Min and Max thickness values. Normally this would be something like a Noise map to give some variation to the interference effect. If this is left blank, the Min parameter specifies the film thickness.
External – refractive index of the medium surrounding the material. Normally this is set to 1.0 for air.
Film – refractive index of the medium that the thin film is made of.
Internal – refractive index of the medium below the thin film.
Gamma – specifies the gamma correction value.
Hue Shift – lets you change colors using a standard Hue spectrum. Range = -180…180.
Saturation – the intensity or purity of the colors. Lowering the Saturation value removes color, causing the color to tend toward grayscale, while raising it intensifies the color.
Range = -100…100.
