Is it possible for using a kinect for motion capture to the bones of rigify? I’m also wondering if Endorphin would work too for rigify 
Probably. The only app/plugin/whatever I’ve seen for this has a list where you can tell motion_capture_bone_x on the motion capture side to correspond to whatever_rig_bone_x on the rig side.
I’ve never seen a good tutorial on setting this stuff up, though.
Rigify bone contains the motion_capture_bone right?
