base classes — bpy_struct, Node, NodeInternal, ShaderNode

class bpy.types.ShaderNodeBsdfHairPrincipled(ShaderNode)

Physically-based, easy-to-use shader for rendering hair and fur

model

Select from Chiang or Huang model

  • CHIANG Chiang – Near-field hair scattering model by Chiang et al. 2016, suitable for close-up looks, but is more noisy when viewing from a distance.

  • HUANG Huang – Far-field hair scattering model by Huang et al. 2022, suitable for viewing from a distance, supports elliptical cross-sections and has more precise highlight in forward scattering directions.

Type:

enum in [‘CHIANG’, ‘HUANG’], default ‘HUANG’

parametrization

Select the shader’s color parametrization

  • ABSORPTION Absorption Coefficient – Directly set the absorption coefficient “sigma_a” (this is not the most intuitive way to color hair).

  • MELANIN Melanin Concentration – Define the melanin concentrations below to get the most realistic-looking hair (you can get the concentrations for different types of hair online).

  • COLOR Direct Coloring – Choose the color of your preference, and the shader will approximate the absorption coefficient to render lookalike hair.

Type:

enum in [‘ABSORPTION’, ‘MELANIN’, ‘COLOR’], default ‘COLOR’
