Create an nHair Transform constraint

You can create a Transform constraint to hold specific nHair curves CVs in place or move them through XYZ space.

To create an nHair Transform constraint

1. In the scene view, select the hair curve CVs you want to constrain. See Select curve components for nConstraints.
2. In the FX menu set, select nConstraint > Transform Constraint .

   The nHair curve CVs you selected are now constrained to their current positions in X, Y, and Z space, and a Transform constraint locator is created for the selected nHair curve components.

   The curves are also now connected to the nHair system's Nucleus solver through a dynamicConstraint node.

   The preset properties on the dynamicConstraint node determine the constraint’s type (in this case, a Transform constraint) and how it behaves. For example, you can create a Transform constraint with the following attribute settings:

   • Spring as the Constraint Method
   • All to First as the Component Relation
   • Within Max Distance as the Connection Method

     Within Max Distance works well with nHair Transform constraints.

   See dynamicConstraintShape.

3. (Optional) Parent the Transform constraint's dynamicConstraint node under the skeleton model to ensure that constraint moves with an animated character.
