Info

title	TIP

Glass can't have coloured reflection or refraction. It reflects and refracts light unaltered. Plastics on the other hand produce coloured reflections and refractions and this colour should be set to the colour of the plastic.

...

This controls the specular roughness (for the GGX BRDF). The larger the value, the rougher is the surface. A roughness of zero generates mirror reflections.

IOR

The index of refraction to use to calculate Fresnel reflections. Higher values generate more prominent specular reflections. Note that there is a separate controls for refractions.

Thin Film

Enables thin-film interference. Thin film interference is a complex phenomena that depends on many variables, including viewing position and usually generates rich patterns on top of the rendered surface. 3Delight performs a physically correct light interference simulation of this phenomena.

Film Thickness

Specifies the thickness of the film in ucm.

Film IOR

Sets the index of refraction of the thin film. This value depends on the material of which the thin film is made. Even if specific index of refractions are needed to simulate real life phenomena (e.g. use an index of refraction of 1.458 for the thin film of silicon dioxide formed on glass because of thermal oxidation) one can simply adjust this value to obtain the desired look.
