Kink displacement works similarly to Frizz, but evaluates noise lookups along the whole length of the guide. The result is a noise pattern that works on a larger scale than the Frizz noise. The effect is similar to crimped hair.

Kink Root—Controls the amount of kink displacement of the hair at its root. Default=0.0. Range=0.0 to 100.0
Kink Tip—Controls the amount of kink displacement of the hair at its tip. Default=0.0. Range=0.0 to 100.0
Kink X/Y/Z Freq(uency)—Controls the frequency of the kink effect on each of the three axes. Default=0.0. Range=0.0 to 100.0.
