Symmetry Modifier 

When working with meshes symmetry is often used to speed up the process by copying changes from one side to another automatically. Similar technique can be applied to Ornatrix strands (hair or guides). You can model only one side of your hair and watch the other side update automatically to reflect the changes.

The best strategy is to use symmetry on guides. Because symmetry doesn't produce any surface information the guides on the other side have to be re-projected onto the surface to get sensible results. This can be done automatically using the Ground Mirrored Strands option.

 

Editing Symmetry Plane 

Use the drop down menu to select the symmetry axis.

 

Parameters 

• Strand Group
  Specifies the group of strands which will be mirrored
• Ignore Distance
  Specifies distance of strands from the symmetry plane which will not be mirrored to the other side.
• Use Ignore Distance
  Toggles strand exclusion based on distance from symmetry plane.
• Ground Mirrored Strands
  When turned on, this option will attempt to automatically place the mirrored strands onto the distribution surface. This allows hair from guides operator to be applied directly above this operator to generate dense hair without having to add a ground strands operator in between.
