Diffuse

DiffuseColour

Defines the basic color of the component, controlled by the DiffuseWeight parameter (see below).

DiffuseWeight

Controls the balance between the DiffuseTexture surface texturing and the light transmitted through the interior of the material. Increasing the value will make the material appear more opaque.

Range: 0.0 – 1.0

DiffuseWeight: 0.0
DiffuseWeight: 0.0
DiffuseWeight: 0.4
DiffuseWeight: 0.4
DiffuseWeight: 0.8
DiffuseWeight: 0.8

Roughness

Controls the size of glossy highlights. Higher values will result in more blurred reflections.

Input: 0.0 – 1.0 or Map

Roughness: 0.0

Absorption

ScatterColour

Controls the color of the inside of the material. Light passing through the material will be absorbed gradually, based on this color. The thicker the object, the more light will be absorbed. A pure white color means there will be no absorption; a pure black color means all light is absorbed as soon as it enters the material. This must be a single color value, it cannot be a texture map or noise function.

Input: Color

ScatterColour: White
ScatterColour: White
ScatterColour: Black

DistanceScale

This value, in meters, controls the overall strength of the subsurface scattering and absorption effects. Reducing this parameter will strengthen the effects. On average, light passing through the material will undergo scattering and absorption each time that it travels this distance through the material.

Range: 0.0 -

DistanceScale: 0.005
DistanceScale: 0.005
DistanceScale: 0.05

Refraction

IOR

Index of Refraction. Controls the amount of ideal (non-glossy) reflection on the surface of the material.

Range: 0.0 – 50.0

IOR: 1.0
IOR: 1.0
IOR: 1.2
IOR: 1.2
IOR: 2.0
