CRAFTING PHYSICALLY-BASED MATERIALS

BASE COLOR/sRGB

Defines the perceived color of an object (sometimes called albedo). More precisely:

→ the diffuse color of a non-metallic object
→ the specular color of a metallic object

METALLIC/GRAYSCALE

Defines whether a surface is dielectric (0.0, non-metal) or conductor (1.0, metal). Pure, unweathered surfaces are rare and will be either 0.0 or 1.0. Rust is not a conductor.

CLEAR COAT/GRAYSCALE

Strength of the clear coat layer on top of a base dielectric or conductor layer. The clear coat layer will commonly be set to 0.0 or 1.0. This layer has a fixed index of refraction of 1.5.

ANISOTROPY/GRAYSCALE

Defines whether the material appearance is directionally dependent, that is isotropic (0.0) or anisotropic (1.0). Brushed metals are anisotropic. Values can be negative to change the orientation of the specular reflections.
