Notice the hairs are quite stiff and stick out from the scalp instead of
naturally falling closer to the scalp. To make the hair appear less stiff you
can either increase the number of Points Per Hair (segments), which
increases the simulation and render time, or you can reduce the Stiffness
value in the hair systems Dynamic attributes.
In the next part of the lesson you adjust dynamic settings of the hair
system, including Stiffness and Gravity, to achieve more naturally
behaving hair.
To improve playback performance and modify dynamic settings
1 In the Attribute Editor (Ctrl + a) select the hairSystemShape1 tab and
change Display Quality to 2. This affects how many hairs display in the
scene view, but has no effect on how much hair appears in the software
render. By reducing the Display Quality, this speeds up the playback of
the hair simulation.
2 In the Dynamics section the default value for Stiffness is 0.10. Since the
hair is quite stiff, reduce the Stiffness value to 0.07.
3 Select Solvers > Interactive Playback to play the simulation. Watch the
hair begin to relax more.
4 With the simulation still playing go to the Dynamics section of the
hairSystemShape1 tab and change the Gravity value to 2.5. Watch the
hair relax even more and rest closer to the scalp, as hair does naturally.
