class UMaterialExpressionStrataSimpleClearCoatBSDF : public UMaterialExpressionStrataBSDF
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FExpressionInput | ClearCoatCoverage | Controls the coverage of the clear coat layer: 0 means no clear coat, 1 means coat is fully visible. |
 |
FExpressionInput | ClearCoatRoughness | Controls how rough the top layer of the material is. |
 |
FExpressionInput | DiffuseAlbedo | Defines the diffused albedo, the percentage of light reflected as diffuse from the surface. |
 |
FExpressionInput | EmissiveColor | Emissive color of the medium (type = float3, unit = luminance, default = 0) |
 |
FExpressionInput | F0 | Defines the color and brightness of the specular highlight where the surface is facing the camera. |
 |
FExpressionInput | Normal | Take the surface normal as input. |
 |
FExpressionInput | Roughness | Controls how rough the bottom layer of the material is. |
