Length Operator 

Length operator modifies the length of guides or hair. It can decrease the size of each strand or increase it by making it longer. Length can be specified on a global level or it can vary through the hair structure depending on user-specified map and channel values.

 

Parameters 

  • Strand Group
    Allows you to isolate the effect of this operator by selecting a particular Strand Group created in the Edit Guides operator.
  • Value
    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.
  • Use Scaling
    When on the strand length will be changed by uniformly scaling all points on the strand, preserving its overall shape.
  • Use Absolute Length
    When on, set absolute strand length value in world units instead of a scaling factor.
  • Scale Width
    When on, the width values of the hair will be adjusted based on how the strand lengths are changed.
  • Value Multiplier
    Here you can use a map to control the length of the hair and create different effects. For example, to have shorter strands where the hair merges with the skin.
  • Minimum Value
    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 Value
    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
    Allows adding some randomness to the strand lengths. Value of 0 means all strands will have the same length value applied. Value of 1 will completely randomize applied strand lengths.
