Editor Properties: (see get_editor_property/set_editor_property)

chain_root (RigElementKey): [Read-Write] The root of the chain to apply the harmonics to
draw_debug (bool): [Read-Write] if True the debug drawing will be enabled
draw_world_offset (Transform): [Read-Write] The world offset to be used when debug drawing
execute_pin (RigVMExecutePin): [Read-Write] This property is used to chain multiple mutable units together
pendulum (RigUnit_ChainHarmonics_Pendulum): [Read-Write] The pendulum settings The harmonic pendulum uses a simple spring interpolation to allow to follow secondary motion.
reach (RigUnit_ChainHarmonics_Reach): [Read-Write] The reach settings Reach lets the chain “lean” towards the target trying to reach it.
speed (Vector): [Read-Write] The speed of the harmonics effects
wave (RigUnit_ChainHarmonics_Wave): [Read-Write] The wave settings A wave is a rocking back and forth motion to be applied to all / some axes.
wave_curve (RuntimeFloatCurve): [Read-Only] The curve to use when evaluating the wave
