MhrEqx weights

mhr.eqx is the MHR (Momentum Human Rig) body model serialised for the JAX/Equinox forward in MhrEqx, loaded with mhr_eqx.mhr.load_mhr_model().

It combines two sources:

• the MHR rig, mesh, blend shapes, skinning and pose correctives, converted from mhr_model.pt of MHR (Apache-2.0);
• the scale and hand-pose PCA and the keypoint regressor of the SAM 3D Body MHR head, from facebook/sam-3d-body-dinov3.

Because it contains SAM Materials, the file is distributed under the SAM License (LICENSE). Publications using it must acknowledge the use of SAM Materials.

ANNY shape arrays

anny/anny_shape_arrays.npz holds the rest-shape buffers of the ANNY body model (NAVER) for mhr_eqx.anny.AnnyShape.from_npz(). It was converted from the anny package 0.6.1 by MhrEqx's scripts/anny/convert_weights.py. Unlike mhr.eqx, it is under the Apache License 2.0 (anny/LICENSE); its mesh assets are adapted from MakeHuman / MPFB2 (CC0). anny/NOTICE lists the contents and changes. Please cite ANNY:
