1.
Add a Surface Follow behavior to the Crowd
object.
2. Add an object or objects to serve as the follow
surface to the scene.

delegate wi ll move to the closest sur face, follow
it to the next closest that it encounters, and then
start following that one, and so on.
3. In the Surface F ollow Behavior rollout,
clickNoneorMultipleSelectiontodesignate
the object or objects whose surface(s) the
