- 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 – 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
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.
