Variables

  Type Name Description
Public variable FExpressionInput Anisotropy Controls the anisotropy factor of the roughness.
Public variable uint32: 1 bUseSSSDiffusion Whether to use light diffusion (i.e., SSS diffusion) or wrap-approximation for material with scattering behavior.
Public variable FExpressionInput DiffuseAlbedo Defines the diffused albedo, the percentage of light reflected as diffuse from the surface.
Public variable FExpressionInput EmissiveColor Emissive color on top of the surface (type = float3, unit = luminance, default = 0)
Public variable FExpressionInput F0 Defines the color and brightness of the specular highlight where the surface is facing the camera.
Public variable FExpressionInput F90 Defines the color of the specular highlight where the surface normal is 90 degrees from the view direction.
Public variable FExpressionInput FuzzAmount The amount of fuzz on top of the surface used to simulate cloth-like appearance.
Public variable FExpressionInput FuzzColor The base color of the fuzz.
Public variable FExpressionInput FuzzRoughness Controls how rough the Fuzz layer is.
Public variable FExpressionInput GlintUV The parameterization of the surface required to position glints on a surface.
Public variable FExpressionInput GlintValue This represent the logarithm of the micro facet density.
Public variable FExpressionInput Normal Take the surface normal as input.
Public variable FExpressionInput Roughness Controls how rough the Material is.
Public variable FExpressionInput SecondRoughness Controls the roughness of a secondary specular lobe.
Public variable FExpressionInput SecondRoughnessWeight The weight of the second specular lobe using SecondRoughness.
Public variable TObjectPtr< class USpecularProfile > SpecularProfile SpecularProfile, for modulating specular appearance and simulating more complex visuals such as iridescence.
Public variable FExpressionInput SSSMFP Chromatic mean free path .
Public variable FExpressionInput SSSMFPScale Scale the mean free path radius of the SSS profile according to a value between 0 and 1.
Public variable FExpressionInput SSSPhaseAnisotropy Phase function anisotropy.
Public variable TObjectPtr< class USubsurfaceProfile > SubsurfaceProfile SubsurfaceProfile, for Screen Space Subsurface Scattering.
Public variable FExpressionInput Tangent Take a surface tangent as input.
