Hey, sorry about the delay, very busy times...
Please import this package and Oculus/SteamVR utilities. Its a demo with VRIK-PuppetMaster setup.
About hanging, did you mean you'd like the hand and head to be locked to the VR controller/HMD, but the lower body hanging freely? I guess it could be done like "Hanging" demo in PuppetMaster with an additional joint between the head and the HMD.
