In this lesson you learned how to:

• Set up objects to collide with hair.

  You can set up hair to collide with itself, the ground plane or other objects. You can even use the Collision Sphere and Collision Cube constraints to establish implicit collisions. For more information, see Make hair collide in the Hair guide.

• Assign a Paint Effects brush to a hair system.

  This is useful for creating a variety of effects, such as vines or ivy for hair. The hair output can be Paint Effects or NURBS curves. For more information, see Assign a Paint Effects brush to Hair in the Hair guide.

• Create constraints on hair curves.

  Use hair constraints to hold hair in position for a hairstyle, such as a ponytail or a clasp. You can even use hair constraints for more realistic hair behavior, such as using the Transform constraint to hold the hair to the head. For more information, see Set up hair constraints in the Hair guide.
