Specular Layer


The SpecularAmount of specular reflection, or the mirror-like reflection of light photons at the same angle. Used for transparent materials such as glass and water. Layer is used for shiny materials like plastics, or clear materials like glass. The Thin Layer option also makes it suitable for clear coats. Refer to the GlossyThe measure of how well light is reflected from a surface in the specular direction, the amount and way in which the light is spread around the specular direction, and the change in specular reflection as the specular angle changes. Used for shiny materials such as plastics or metals., Specular, and Universal MaterialThe representation of the surface or volume properties of an object. topics in this manual for more information.




Specular Layer Parameters

Specular - The layer's coating color.

TransmissionA surface characteristic that determines if light may pass through a surface volume. - The layer's transmission color.

BRDF Model - Determines how light reflects or refracts. See BRDF Models for details.

Roughness - The layer's roughness.

Affect Roughness - The percentage of roughness affecting the subsequent layer's roughness.

Anisotropy - The layer's anisotropy. A value of -1 is horizontal, while 1 is vertical. A value of 0 is Isotropic.

Rotation - The rotation of the specular anisotropic reflection.

IOR - The specular reflection's or transmission's Index Of Refraction.

1/IOR Map - The Index Of Refraction map. Each texel represents 1/IOR. When this is not empty, it overrides the IOR setting.

Film Width - Sets the film coating's thickness.

Film IOR - Sets the film coating's Index Of Refraction.

Thin Layer - Makes the layer very thin so it reflects, or goes straight though the layer.

Bump - Creates fine surface detail by simulating a relief using a Greyscale texture interpreted as a height map.

Normal - Creates fine surface detail by distorting normals using an RGB image.

Dispersion Coefficient - This is the B parameter of the Cauchy dispersion model. Increasing this value increases the coloration amount and dispersion in the layer's transmission and caustics.

Layer Opacity - Controls the layer's opacity with a Greyscale texture.
