Edit nHair constraints

Editing nHair constraint membership

You can add, remove, or replace the components that are used in your nHair constraint by editing constraint membership. You cannot, however, add an object to an existing constraint by editing constraint membership.

To edit constraint membership, you can use the Replace Members, Add Members, and Remove Members options, or the nConstraint Membership Tool.

To see the members and links of a selected constraint

1. In the Outliner, select the dynamicConstraint node of the constrained hair curves for which you want to edit dynamic constraint membership.
2. Select nConstraint > Select Members.

   The component members and links of the selected constraint highlight in the scene view.

To edit nHair constraint membership

1. Using the component selection mode that is appropriate for the type of component you want to edit, select the constrained object’s components you want add, remove, or replace.

   For example, if you want to edit the membership of a Component to Component constraint that links curve CVs, you would use Vertex selection mode.

2. If your constrained object has only one constraint, do one of the following:
   • If you want to add the selected components to the constraint, select nConstraint > Add Members.
   • If you want to removed the selected components from the constraint, select nConstraint > Remove Members.
   • If you want to replace all the current constraint members on the selected object with the selected components, select nConstraint > Replace Members.
     Note

     If a "Multiple constraints for selected items. Additionally select the constraint node to edit", message appears, it means that your object has more than one constraint. See step 3.

3. If your constrained object has two or more constraints, you need to specify which constraint you want to edit. With your object's components still selected, do one of the following:
   • In the scene view, -click the constraint you want to edit.
   • In the Outliner, -click the select the dynamicConstraint node of the constraint you want to edit.

   You can now edit the selected constraint’s membership by selecting nConstraint > Add Members, nConstraint > Remove Members, or nConstraint > Replace Members.

To use the nConstraint Membership Tool to edit dynamic constraint membership

1. In the Outliner, select the dynamicConstraint node of the constrained nHair object for which you want to edit dynamic constraint membership.
2. In the Attribute Editor, select the tab for the specific dynamic constraint (dynamicConstraint) you want to edit the membership for and click Select.
3. In the nDynamics menu set, select nConstraint > nConstraint Membership Tool.
4. Do one of the following:
   • Select the constrained curve CVs with which you want to replace the current members of the selected dynamic constraint.
   • -click the curve CVs you want to add to the selected dynamic constraint.
   • -click the curve CVs you want to remove from the selected dynamic constraint.
5. Press to complete the replace, add, or remove dynamic constraint members operation.
