SMPL_BODY_BONES

Hi,

I wonder why the joint names in SMPL_BODY_BONES is different from the official SMPL (e.g., the 'left_hand', 'right_hand' is commented) ?

Thanks.

Hi @cjfcsjt, thank you for your question!

In our pipeline, the 3d human models to be animated are created via the official SMPL-X Blender Add-on. We map the names of SMPL to their counterparts of SMPL-X.

But for bones of left_hand and right_hand which in SMPL-X have been divided into finger bones such as left_index1 and left_thumb1, their motions couldn't be properly used to drive a SMPL-X model, so they are ignored for simplicity.
