ShaderNodeBsdfPrincipled(ShaderNode)

base classes — bpy_struct, Node, NodeInternal, ShaderNode

class bpy.types.ShaderNodeBsdfPrincipled(ShaderNode)

Physically-based, easy-to-use shader for rendering surface materials, based on the Disney principled model also known as the “PBR” shader

distribution

Light scattering distribution on rough surface

  • GGX GGX.

  • MULTI_GGX Multiscatter GGX – Slower than GGX but gives a more energy conserving results, which would otherwise be visible as excessive darkening.

Type

enum in [‘GGX’, ‘MULTI_GGX’], default ‘GGX’

subsurface_method

Method for rendering subsurface scattering

  • BURLEY Christensen-Burley – Approximation to physically based volume scattering.

  • RANDOM_WALK_FIXED_RADIUS Random Walk (Fixed Radius) – Volumetric approximation to physically based volume scattering, using the scattering radius as specified.

  • RANDOM_WALK Random Walk – Volumetric approximation to physically based volume scattering, with scattering radius automatically adjusted to match color textures.

Type

enum in [‘BURLEY’, ‘RANDOM_WALK_FIXED_RADIUS’, ‘RANDOM_WALK’], default ‘BURLEY’
