Produce a hair BSDF.
The Hair Model VOP combines all three BSDFs to get the overall hair effect.
The secondary reflection differs from the primary reflection as it provides additional controls for glints. Glints are sharp highlights that occur in pairs around the hair’s axis.
Specify a label for the BSDF component. Labels are currently ignored by mantra, but may be used in the future to separate components into deep raster planes.
The reflectivity of the color components (red, green, and blue). For
Controls the angular spread of the reflection. Low values result in reflection over a narrow cone of angles, and high values result in reflection over a broader cone.
Controls the general direction of the reflection. Values range from
The relative intensity of the glints, compared to the reflection lobe. This parameter gives you independent control of the glint and overall reflection intensities.
Controls the angular spread of the glints. Low values result in reflection over a narrow cone of angles, and high values result in reflection over a broader cone.
Controls the angular separation of the glints. Values range from
Normalized surface normal.
