Node
...
The BRDFCarPaint node provides inputs for controlling various material properties. They correspond to parameters in the section below.
Base
...
Double Sided – When enabled, the material is double-sided.
Color – The Specifies the diffuse color for the base layer.
Reflection – The Specifies the reflectivity of the base layer. The reflection color itself is the same as the Base color.
Glossiness – Reflection Specifies reflection glossiness for the base layer.
Bump Type – Specifies whether a bump map or a normal map effect will be is added to the base material.
...
Trace Base Reflection – Toggles reflections for the base layer
Coat
...
Strength – The Specifies the strength of the coat reflections when the surface is viewed directly from the front.
Color – The Specifies the color of the coat layer.
Glossiness – Glossiness Specifies the glossiness of the coat reflections.
Bump Type – Specifies whether a bump map or a normal map effect will be is added to the base material.
...
Explicit – The flakes are mapped using the specified channel.
Triplanar – The material automatically computes mapping coordinates in object space based on the surface normals.
Mapping Channel – The Specifies the mapping channel for the flakes when the Flake mapping type is set to Explicit mapping channel.
Color – The Specifies the color of the metal flakes.
Glossiness – The Specifies the glossiness of the metal flakes. It is not recommended to set this above 0.9 as it may produce artifacts.
Orientation – Controls the orientation of the flakes relative to the surface normal. When this is 0.0, all flakes are perfectly aligned with the surface. When it is 1.0, the flakes are rotated completely randomly with respect to the normal. Values above 0.5 are not recommended as they can produce artifacts. For more information, see The Flake Orientation Parameter example below.
Density – The Specifies the density (number of flakes) for a certain area. Lower values produce less flakes and higher values produce more flakes. Set this to 0.0 to produce a material without flakes. For more information, see The Flake Density Parameter example below.
Scale – Scales the entire flake structure. For more information, see The Flake Scale Parameter example below.
Size – The Specifies the size of the flakes relative to the distance between them. Higher values produce bigger flakes and lower values produce smaller flakes. For more information, see The Flake Size Parameter example below.
...
Trace Flakes Reflections – Toggles reflections for flake layer.
Options
...
Trace Reflections for All Layers – When enabled, reflections will be are traced for all layers of the Car Paint material.
