Create an nHair Force Field constraint

You can create a Force Field constraint to push nHair curve CVs away from the center of the constraint, in a radial field with spherical volume bounds. For example, you can push out specific hair curves to create a general shape for a hair style.

To create a Force Field constraint

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

   The Force Field locator appears near the selected hair curves, and the dynamicConstraint node appears in the Attribute Editor.

   
3. Adjust the location, size and rotation of the Force Field constraint using Maya’s Move, Scale, and Rotate tools.

   The location, size, and rotation of the locator determines the size, shape and volume of the force field constraint.

4. (Optional) Adjust the Force, Strength and Strength Dropoff attributes on the dynamicConstraint node to determine the power of the force field. Positive values cause the force field to push out, while negative values cause the force field to suck in hair curves.
