ShaderNodeBsdfHairPrincipled(ShaderNode)

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 (default 'HUANG')

  • 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 – Multi-scale hair scattering model by Huang et al. 2022, suitable for viewing both up close and from a distance, supports elliptical cross-sections and has more precise highlight in forward scattering directions..

Type:

Literal[‘CHIANG’, ‘HUANG’]

parametrization

Select the shader’s color parametrization (default 'COLOR')

  • 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:

Literal[‘ABSORPTION’, ‘MELANIN’, ‘COLOR’]
