Hi @KevinLTT , Thanks for your work! I was stuck in a issue when I use pose2bvh to convert our 3d pose to bvh which is used to finish motion retargeting: bad retargeting result is generated so I compared input: our bvh and Mixamo bvh, here are their T-poses:

 picture 1 is our generated T-pose,  picture 2 is Mixamo's T-pose,  seems their local axis in legs  is reversed,  how can I convert leg's local axis to  be same as Mixamo's?  when use pose2bvh  I did some changes: use right-hand coordinate instead of left-hand coordinate.
 Expect  your reply sincerely , thanks!

regards, summer Gao

Hey @birdflies, @summer-wind-hi, I'm facing the same issue now. I've been experimenting with rolling the leg bones in Blender, but haven't been able to do so successfully (when I roll the bones in Edit Mode, it somehow moves the tail of the bone when back in Object mode).

Did either of you ever make a breakthrough here?
