Coat Color– Determines the coat layer's color. The Coat Color tints all layers - reflection, sheen, diffuse and refraction. Note that the coat specular highlights are not affected and are always white. A texture map can be used here. See the Coat Color example below for more information.
Amount – Specifies the blending weight of the coat layer. A value of 0 does not add a coat layer, while higher values blend the coat gradually. See the Coat Amount example below for more information.
Coat glossiness – – Controls the sharpness of reflection. A value of 1.0 means perfect glass-like reflection; lower values produce blurry or glossy reflections. See the Coat Glossiness example below for more information.
IOR – Specifies the Index of Refraction for the coat layer.
Lock coat bump to base bump – When enabled, it prioritizes the base bump map during rendering over the coat bump map. You can use it to temporarily hide the coat bump.
Bump Map Type – Allows the user to specify whether a bump map or a normal map effect is added.
Bump Map Normal map in tangent space Normal map in object space Normal map in screen space Normal map in world space Local space bump map
Bump Map – Specifies the bump/normal map used as a coat bump.
Coat Bump Mult – A multiplier for the bump effect.
