Coating Parameter Group

The Coating group provides parameters that let you define a Clearcoat layer on top of an appearance. A Clearcoat is a glossy and transparent coating that forms the finishing layer on the surface. You commonly apply to woods and paints.

Clearcoat

Name Clearcoat
Type Decimal
Range [0..1]
Usage Uniform Value or Grayscale Texture

Clearcoat Roughness

Name Clearcoat Roughness
Type Decimal
Range [0..1]
Usage Uniform Value or Grayscale Texture
Description Clearcoat Roughness determines the level of roughness of a Clearcoat layer, on a scale from 0 to 1, where 0 is shiny and 1 is very rough.

Recommendation: Specify 0 or a very small value, although the parameter supports any value between 0 and 1.

Clearcoat Normal

Name Clearcoat Normal
Type 3D Vector
Range X: [0..1], Y: [0..1], Z: [0..1]
Usage Normal Texture only (DirectX convention)
Description The Clearcoat feature includes a distinct Normal parameter known as Clearcoat Normal, which functions identically to the Normal parameter in the Base group.

There are two standard formats of Normal textures, DirectX and OpenGL. Both have the same capability only their green channel is flipped. SOLIDWORKS Visualize and SOLIDWORKS both follow the DirectX normal textures convention. If you use OpenGL textures instead, shadows incorrectly display rotated at 90 degrees.
