Reflection

Color

Specifies the color for reflections.

Roughness

This controls the specular roughness. The smaller the value, the smoother is the surface.

^{Roughness 0.0}

^{Roughness 0.1}

^{Roughness 0.2}

Samples

Specifies how many samples to trace for reflection.

IOR

The IOR to use to calculate Fresnel reflections.

^{IOR 1.2}

^{IOR 1.6}

^{IOR 2.0}

Refraction

Color

The color of the refraction. Setting this color to 0 disables refraction.

^{Color 0.9 0.9 0.95}

^{Color 0.72 0.72 0.85}

^{Color 0.43 0.43 0.7}

Roughness

Specifies the roughness of the refraction. The smaller the value, the smoother is the surface. Higher values can be used to emulate "ground glass" for example.

^{Roughness 0.02}

^{Roughness 0.05}

^{Roughness 0.1}

Attenuation

Attenuation Strength

^{Attenuation Strength 3}

^{Attenuation Strength 6}

^{Attenuation Strength 12}

Samples

Specifies how many samples to trace for refraction.

IOR

The index of refraction of the glass.

^{IOR 1.2}

^{IOR 1.4}

^{IOR 1.6}

Diffuse

Color

This diffuse colour of the material.

^{Color 0.2 0.2 0.2}

^{Color 0.6 0.6 0.6}

^{Color 1.0 1.0 1.0}

Roughness

This controls how diffuse is the material. A value closer to one simulate very rough material. A value of 0 renders a standard "lambertian" diffuse. On a more technical note, this paramter controls the roughness of the Oren-Nayer diffuse model.
