Detailed hand/finger poses

[jyf588]

Hello authors!

Great job on all your effort in creating this large dataset! I was trying to play around with it by first loading and visualizing the motions.

For some reason I noticed some issues with the hand motions, for example
In the 1st screenshot, right hand is grabbing the bottle fine, but left hand has unnatural finger poses
In the 2nd screenshot, the hand is not really grasping the bottle
In the 3rd screenshot, bottle is too long and penetrating the body mesh

Could you let me know if this is expected or there might be something I was doing it wrong? Thanks so much!

For reference, here is my code snippet for loading the SMPL motions:

smplx_model: SMPLX = smplx.create(
        model_path=cfg.model_path,
        model_type="smplx",
        gender="neutral",
        batch_size=t_end - t_start,
        use_pca=False,
    )
smplx_output: SMPLXOutput = smplx_model.forward(
        betas=all_betas[t_start:t_end],
        transl=all_human_transl[t_start:t_end],
        body_pose=all_human_poses[t_start:t_end],
        global_orient=all_human_orient[t_start:t_end],
        return_verts=True,
        return_full_pose=True,
        left_hand_pose=all_left_hand_poses[t_start:t_end],
        right_hand_pose=all_right_hand_poses[t_start:t_end],
    )
