Use Hair presets

Select nHair > Get Hair Example to choose from hair presets (wigs), styled hair systems that you can import and attach to surfaces. Each example file includes:

• A full hair system (see hairSystemShape for details on the hair system)
• A base surface that temporarily hosts the hair system.
  NoteTo have the base surface collide with nHair, convert it to a passive collision object by selecting the surface and selecting nMesh > Create Passive Collider.
• A hair constraint collision sphere, if it is necessary for the preset.
  NoteClassic Maya Hair constraints are not supported by the Nucleus solver and have no effect on nHair simulations. To reproduce the behavior of classic hair, you may need to create an nConstraint to replace classic the Hair constraint.

  See Create nHair constraints.

Modify these files to customize hair styles and behavior, use them as learning tools to understand how to create your own hair styles, or use them simply for ideas.

To import a Hair preset into a scene

1. In the nDynamics menu set, select nHair > Get Hair Example. The Visor window opens to the Hair Examples tab.
2. Right-click the desired Hair preset and select Import. Maya imports the hair system and its surface into your scene. See To transplant a Hair Preset to another surface.

   The Notes section at the bottom of the Attribute Editor provides information about the Hair preset, pointing out the key aspects of its construction.

   
3. In the Outliner, select the hairSystem node, and select nSolver > Assign Solver > New Solver.

   You can assign the hair preset to an existing Nucleus solver, by selecting the solver from the Assign Solver list.

4. Play the simulation.

   To preserve the start shape, some hair presets may require that you increase the hairSystemShape node Stretch Resistance, Compression Resistance, Bend Resistance, and Twist Resistance attributes. See hairSystemShape.

   If you are trying to re-create the behavior of your classic Hair simulation, you can toggle the Use Nucleus Solver attribute (hairSystemShape node) on and off as you simulate the nHair. This way, you can quickly compare the classic Hair and nHair versions of your simulation.
