The Fur Sampler node contains unique outputs listed below. These outputs are accessed by right-clicking the node in the Hypershade window and selecting Show All Attributes, or left clicking the output master port and selecting Other....
Distance Along Strand – Used to control color or information along the length of the strand. Provides information about the shaded part of the fur strand. For the base of the strand, the value is 0.0. For the tip, it is 1.0. With this option, a gradient can be mapped along each strand regardless of each strand's length. Distance Along Strand Absolute – Provides information about the shaded part of the fur strand. This option uses the Fur Max Distance parameter to allow length-dependent mapping using absolute distance. For instance, when used with a gradient this allows for all fur strands regardless of length to have a root color all up to the same length followed by the rest of the gradient. Position Across Strand – Allows textures to be mapped across each strand. Random By Strand – Used to add variation in strands. Provides a unique random floating point value for each strand in the fur system, which allows shading each strand with a random color sampled from a texture. Fur 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 fur. This option is mappable, allowing different parts in a fur system to have different max lengths. |
