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
 
Non-metal range
10 - 240
 
 
Metal range
170 - 255

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.

| NON-METAL/DIELECTRIC | METAL/CONDUCTOR |
Defines the perceived smoothness (0.0) or roughness (1.0). It is sometimes called glossiness.

Specular intensity for non-metals. The default is 0.5 , or 4% reflectance.

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.

|---|---|---|---|---|---|---|---|---|---|---|
| NO CLEAR COAT | FULL CLEAR COAT |
Defines the perceived smoothness (0.0) or roughness (1.0) of the clear coat layer. It is sometimes called glossiness. This may affect the roughness of the base layer.
| 0.0 | 0.1 | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 0.9 | 1.0 |
|---|---|---|---|---|---|---|---|---|---|---|
| GLOSSY CLEAR COAT | ROUGH CLEAR COAT |
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.
