Assign hair constraints

User Guide > Dynamics and Effects > Hair > Modifying hair >

NoteThe hair follicles you want to assign your hair constraint to must be part of the same hair system. You cannot assign hair constraints to multiple hair systems.

However, you can make multiple hair constraints that are assigned to multiple hair systems act like a single constraint by parenting your constraints to a single constraint, and then hiding the child constraints.

To assign hair constraints

Select the hair constraint you want to assign and then Shift-select the follicles to which you want to assign the constraint.
Select Hair > Assign Hair Constraint > .
The Assign Hair Constraint Options window appears. See Hair > Assign Hair Constraint.
Set the Assign Hair Constraint Options as you desire.
Do one of the following:
- Click Assign Constraint to assign the selected hair constraint to the selected hair follicles. The Assign Hair Constraint Options window closes.
- Click Apply to assign the selected hair constraint to the selected hair follicles. The Assign Hair Constraint Options windows remains open.
- Click Close to cancel the Assign Hair Constraint operation and close the Assign Hair Constraint Options window.
If you clicked Assign Constraint or Apply, the selected follicles are added to the selected hair constraint or the hair constraint is reassigned to the selected hair follicles.
