Play a hair simulation
To see how hair and dynamic curves react when
forces are applied to them, play the simulation. To make changes
to the hair system or follicle attributes while the simulation is
running, use Interactive Playback.
To tweak the hair simulation, adjust the Stiffness, Iterations,
and even Gravity attributes in the Dynamics section
of the hairSystemShape. The Damp value
can be adjusted to relax oscillating curves on non-straight hair.
See
Dynamics.
NoteThere may be performance issues with playback
if output is set to NURBS curves and the number
of curves is high. As a workaround to provide faster interactive
feedback, create hair with output set to Paint Effects and NURBS
curves, and hide the group containing the output curves.
Then in the hairSystemShape, set the Hairs Per Clump to
1 and the Clump Width to 0.
To
play the simulation
- Increase
your frame range, for example, to 1000.
- Select
Hair > Display > Current
Position.
- Click
the Play button to play the simulation.
Watch the hair react to dynamic forces as the simulation plays.
To
play and interact with a hair simulation
- Increase
your frame range, for example, to 10000.
- Select
Solvers > Interactive Playback.
- Interact
with the hair simulation while it’s running, including modifying dynamic
hair system and follicle attributes, as well as transforming the surfaces
to which the hair or dynamic curves are attached to see how the hair
behaves.
- Click
the Stop button to stop the simulation.
