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.
