Amount – Specifies the thickness amount of the coat layer. A value of 0 does not add a coat layer, while higher values blend the coat gradually.

Color – Specifies the color or map of the coat layer.

Glossiness – Specifies the glossiness value or map of the coat reflections.

IOR – Specifies the Index of Refraction for the coat layer.

Bump Type – Specify whether a bump map or a normal map effect is added to the coat material.

Normal (Object)

Explicit Normal

Bump Strength – Specifies a multiplier for the bump/normal effect.

Trace Coat Reflections – When disabled, the clear coat only produces specular highlights, but no actual reflections.

Color – Specifies the color or map of the metal flakes.

Orientation – Specifies the orientation value or map of the metal flakes. The orientation of the flakes is relative to the surface normal. When set to 0.0, all flakes are perfectly aligned with the surface. When set to 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. See the Flake Orientation example below.

Flake Orientation Tail – Controls the transition from highlighted areas to non-highlighted areas.

Density – 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. See the Density example below.

Scale – Scales the entire flake structure. See the Scale example below.

Size – Specifies the size of the flakes relative to the distance between them. Higher values produce bigger flakes and lower values produce smaller flakes. See the Size example below.

Map Size – Internally the material creates several bitmaps to store the generated flakes. This parameter determines the size of the bitmaps. Lower values reduce RAM usage, but may produce noticeable tiling in the flake structure. Higher values require more RAM, but tiling is reduced.

Seed – The random seed for the flakes. Changing this produces different flake patterns.

Flake Glossiness – Specifies the reflection glossiness value of the flakes.

Double-Sided – When enabled, it makes the material double-sided.

Trace Reflections for All Layers – Global switch to toggle reflections for all layers.

Trace Depth – Specifies the number of times a ray can be reflected.

Cutoff – Specifies the cutoff threshold for the reflections of the different layers.

Use Environment Override – Enables the use of Environment override textures.

Environment Override – Specifies an Environment override texture.

Environment Priority – Specifies the Environment override priority when several materials override it along a ray path.
