This component is designed to represent the reflectance properties of non-metals such as plastics, ceramics and glass. It is similar to the Dielectric component, but allows the creation of advanced glossy reflections that have two 'lobes' or highlights of different sizes.
Dielectric materials follows Fresnel's Law where the amount of reflectance varies based on the angle of view. For example, viewing a carbon fiber type object at very shallow angles results in almost complete reflectance whereas looking straight on, the object exhibits less reflectance. This Fresnel falloff can be defined explicitly by setting reflectance values for 0 degrees (e.g. looking at the middle of a sphere object) and 90 degrees (looking at the edge of a sphere). You can define how quickly the falloff varies between 0 and 90 via an exponent parameter. The Fresnel effect can also be specified by using an IOR value which effectively fills the above values in for you.
This is the same as the TwoLobeAnisoDielectric component without additional control over Anisotropy.
The basic color of the component. This can be a single color value or a texture map.
Input: Map/Color
Can be used to control the color of reflections or using greyscale, the amount of reflections.

Controls the size of the glossy highlights for the primary lobe. Higher values will make the reflections appear more blurred.
Range: 0.0 - 1.0 or Map

Controls the size of the glossy highlights for the secondary lobe. Higher values will make the reflections appear more blurred.
Range: 0.0 - 1.0 or Map

Controls how quickly the shininess changes between the normal and grazing values as you move across the surface.
Range: 0.01 - 25.0

This parameter controls how shiny the object appears looking straight on. Typical materials of this type display little reflectance at 0 degrees.
Range: 0.0 - 1.0 or Map

This parameter control how shiny the object appears looking at a very shallow angle. Typical materials of this type display higher reflectance at 90 degrees to the camera.
Range: 0.0 - 1.0 or Map

Input: On/Off Checkbox
Ignores the normal, grazing values and exponent, and uses the IOR value to define the falloff curve.
Range: 0.0 - 50.0
Index of Refraction. Controls the amount of reflection and shape of the falloff curve, Use IOR must be checked.
