The Disney Principled Shader is a widely used material in the VFX, Animation and Game Industry that offers an artist-friendly set of parameters.
Attribute |
Description |
Base Color |
Defines the surface color. |
Roughness |
Surface roughness: controls diffuse, specular and transmission response. |
Metallic |
The metallic-ness (0 = dielectric, 1 = metallic). This is a linear blend between two different models. The metallic model has no diffuse component and also has a tinted incident specular, equal to the base color. |
Specular |
Incident specular amount. |
Specular Tint |
Tints incident specular towards the base color. Grazing specular is still achromatic. |
Anisotropic |
Degree of anisotropy. This controls the aspect ratio of the specular highlight (0 = isotropic, 100 = max anisotropic). |
Anisotropic Rotation |
Rotates the direction of anisotropy, with 1.0 going full circle. |
Clear Coat |
A second, special-purpose specular lobe. |
Clear Coat Glossiness |
Controls clear coat glossiness (0 = "satin" appearance, 100 = a "gloss" appearance). |
Specular Color |
Defines the specular color. |
Metallic Edge Color |
Color bias as the viewing direction becomes parallel to the surface. |
Reflection Exit Color |
Sets the reflection color when there is no more bounce along the path. |
Subsurface |
Controls diffuse shape using a subsurface approximation. |
Subsurface Color |
Defines the scattering color inside the material. |
Subsurface Radius |
Sets the light penetration distance inside the material. |
Subsurface Group |
Name of the group among which illumination propagates between SSS materials. |
Transmission |
An additional transmissive component. |
Transmission Tint |
Amount to tint transmission towards base color. |
Transmission Color |
Defines the transmission color. |
Transmission Exit Color |
Sets the transmission color when there is no more bounce along the path. |
Sheen |
An additional grazing component, primarily intended for cloth. |
Sheen Tint |
Amount to tint sheen towards base color. |
Sheen Color |
Defines the sheen color. |
Emission |
Strength of the emission. |
Emission Color |
Defines the emission color. |
