Overview

_{Length modifier (left to right): not applied, applied with a random factor of 0.5, applied with a fractal noise map controlling the length}

Hair length plugin is used for one simple purpose- to parametrically or manually change the length of a dense hair model. Note that it is only possible to shorten the hair, not make it longer. That is because hair length uses only the provided info; it cannot extrapolate new information. You can control hair length either through a random factor, or through a monotone texture map. Texture map will the the UV coordinates or world coordinates of the hair (whichever ones are available).

Parameters

Length

Multiplier for strand lengths. Value of 1 means the length remains the same. Value of 0.5 means the strands will be half as long.

Minimum Length

After applying randomization and maps the value will not be allowed to be lower than this parameter. Use this to clamp the size of short strands.

Maximum Length

After applying randomization and maps the value will not be allowed to be higher than this parameter. Use this to clamp the size of long strands.

Randomize

Determines how random the relative hair length should be. A value of 0 leaves hair as it is, a value of 1 completely randomizes hair length.

MaxScript Access

You may use standard properties exposed by showProperties myModifier to access and change this modifier.
