This document describes the Physics Motion Enhance tool. This is a tool that will add a spring like physics/dynamics effect onto a group of 2 or more bones. This tool allows you to easily animate directed motion and then add on top of it the desired bouncy, physics type motion. It can be very useful for wanting to add any sort of spring/bounce type effect to your existing animation.


  • Stable End Enabling this makes the end bone target existing animation and behave in a more stable fashion

  • Stiffness How stiff the bending forces are on the chain of bones.

  • Stretch Stiffness How stiff the stretching forces are on the chain of bones.

  • Damping How quickly the system calms down and loses energy. In general the stiffer the system, the higher you should set your damping values.
