3 To create the collision constraint for Marions upper torso, do the
following:
Using the Select Tool, drag around the hair curves and select Hair >
Convert Selection > To Start Curves.
Select Hair > Create Constraint > Collide Sphere.
Using the Scale Tool, resize the sphere so it extends beyond Marions
neck and you can see it.
Using the Move Tool, move the sphere down the Y-axis so the top of
the sphere is aligned with the top of Marions torso.
Using the Scale Tool again, resize the sphere so it matches the basic
dimensions of Marions upper torso. First try scaling in the X direction
to adjust the width of the sphere from shoulder to shoulder. Then
tumble the camera to see the side of Marions head and scale in the
Z direction to adjust the sphere width from the back of Marions torso
to the front of it. You may also need to move the sphere to tweak its
size and position, as shown in the images below.
