This page provides information about the Hair Sampler node in V-Ray for Cinema 4D.
Overview
The Hair Sampler is an utility node that provides extra output options which can be used when shading hair.
Used with the Hair Next node, this node allows you to map color, incandescence, and transparency along the length of a hair strand, as well as the ability to randomize such properties on a per-strand basis to create stunning hair looks.
Parameters
Hair Max Distance – Allows the user to set the max strand length when using Distance Along Strand Absolute. Typically, this value should be equal to the longest strand of hair. This option is mappable, allowing different parts in a hair system to have different max lengths.
