Hi - same problem here - it's maddening.
I record with xsens awinda and manus cloves. The data/movement looks great in xsens, the hands and body record perfectly, so it's not a problem with the gloves - its just when I try to import it via motionlive to iclone, the hands are completely warped. Is it a problem with the bones?
I've tried using generic human bodies from character creator to ensure it's nothing wrong from my end - but the same problem.
I have the latest version of iclone 7.93 and a beast of a machine.
For now I just redo the hands manually with Gestures or the Hand puppeteering
Ideas or help would be appreciated!
