Hi! @wqyin I use SMPLer-X to get SMPLX and convert it to SMPLH, no the parameters of SMPLH is 'betas'(16),'body_shape'(189),"left_hand_pose" (135) and 'left_hand_pose' (135) the joints number is 73, I wonder how to use joint positions to get SMPLH parameter(or mesh) to reconstruct SMPLH model. Does this project have code for this functionality?
