Mixing between the options for roots and tips. The blending ratio is set along the hair using a spline and a one-dimensional texture map.
Reflection Intensity
The intensity of the first reflection from the surface of the hair.
Reflection Tint
Hue of the first reflection from the surface of the hair.
Reflection Tint 2
Hue after the second reflection from the far surface of the hair. The beam at the same time goes back into the volume of the hair.
Roughness
Roughness of the hair surface. The spline additionally changes the roughness value depending on the wavelength.
Anisotropy
Roughness anisotropy (difference in roughness along the hair compared to the direction across). The spline additionally changes the anisotropy value depending on the wavelength.
Shift angle
Emulates stepped hair.
IOR
Refractive index in the hair dielectric. The spline additionally changes the IOR value depending on the wavelength.
