How to fit the generated motion of KIT dataset to smpl

[qiqiApink]

I have generated motion with 21 joints 3d positions and I wonder how to fit them to smpl. It seems that the codes provided only work on HumanML3D.

Hello @qiqiApink,

In this work, we do not fit skeletons to SMPL. We generate the motions directly in the SMPL format (see the kit-amass-rot data loader option).

If you want to generate skeletons and fit them to SMPL, you can check other works (like MDM where they use SMPLify optimisation algorithm on top of the generated motions).
