Inputs

Name	Description	Permitted Types	Default Value
ChainRoot	The root of the chain to apply the harmonics to	Rig Element Key	(Type=Bone,Name="")
Speed	The speed of the harmonics effects	Vector	(X=1.000000,Y=1.000000,Z=1.000000)
Reach	The reach settings Reach lets the chain "lean" towards the target trying to reach it.	Rig Unit Chain Harmonics Reach	(bEnabled=False,ReachTarget=(X=0.000000,Y=0.000000,Z=0.000000),ReachAxis=(X=1.000000,Y=0.000000,Z=0.000000),ReachMinimum=0.000000,ReachMaximum=0.000000,ReachEase=Linear)
Wave	The wave settings A wave is a rocking back and forth motion to be applied to all / some axes.	Rig Unit Chain Harmonics Wave	(bEnabled=True,WaveFrequency=(X=1.000000,Y=0.600000,Z=0.800000),WaveAmplitude=(X=0.000000,Y=1.000000,Z=0.000000),WaveOffset=(X=0.000000,Y=1.000000,Z=2.000000),WaveNoise=(X=0.000000,Y=0.000000,Z=0.000000),WaveMinimum=0.000000,WaveMaximum=1.000000,WaveEase=Linear)

Pendulum	The pendulum settings The harmonic pendulum uses a simple spring interpolation to allow to follow secondary motion.	Rig Unit Chain Harmonics Pendulum	(bEnabled=False,PendulumStiffness=2.000000,PendulumGravity=(X=0.000000,Y=0.000000,Z=0.000000),PendulumBlend=0.750000,PendulumDrag=0.980000,PendulumMinimum=0.000000,PendulumMaximum=0.100000,PendulumEase=Linear,UnwindAxis=(X=0.000000,Y=1.000000,Z=0.000000),UnwindMinimum=0.200000,UnwindMaximum=0.050000)
bDrawDebug	if True the debug drawing will be enabled	bool	True
