Abstract

We present the Meta Momentum Human Rig (MHR), a parametric human body model that combines the decoupled skeleton/shape paradigm of ATLAS with a flexible, modern rig and pose corrective system inspired by the Momentum library. Our model enables expressive, anatomically plausible human animation, supporting both linear and non-linear pose correctives, and is designed for robust integration in AR/VR and graphics pipelines. This model is the output representation of Sam 3D Body a robust promptable foundation model for single-image full-body 3D human mesh recovery (HMR).
