Define Rig Manually
Maybe it would be easier, and more accurate, if we could define the righ based on any frame. For example, if I want to get the animation of a dance that envolves two people, I could define the rif of one of them, and maybe the result would be so much better, also if the legs aren't seen on screen there are a lot of problems and so. It would be so much better to have an option to define the righ based on a frame. So we pose the rig like it is in the video, and then your application does the magic, and does it perfect.
