respond to the motion of the body it ’s attached
to as well as external influences such as w ind and
gravity. Hair’s Dynamics functions let the hair
behave as real-world hair, in interactive (Live) or
Precomputed mode.
Mode—The method Hair uses to generate
dynamics. Livemodeissuitablefor
experimentation, but Precomputed should
be used for rendering animation with Hair.
• None: Hair doesn’t simulate dynamics.
• Live: Hair simulates dynamics interact ively in
the view p orts, but doesn’t generate animation

best results with Live mode, turn off Display
rollout > Display Hairs group > As Geometry,
if necessary.
For some methods of using live dynamics,
see this procedure:
Example: To view hair

.
• Precomputed:Letsyougeneratestatfilesfor
rendering dynamics-animated hair. Available
only after setting a name and location for
stat files (see following and

precomput ed dynamics simulation with Hair:

).
Stat Files group
Stat files let you record and play back a
Hair-generated dynamics simulation. For a
workflow example, see this procedure:
