WHAM outputs world-grounded SMPL motion and MDM exports SMPL parameters and .obj frames, while Blender's Rigify documentation covers generating production rigs from metarigs. No fetched source describes retargeting between the two or cleanup of foot sliding and noise.

Why this is still open: Estimation papers evaluate joint error, not downstream animator-ready rig quality; no documented recipe was found.
