SMPL-X (SMPL eXpressive) is a unified body model with shape parameters trained jointly for the face, hands and body. SMPL-X uses standard vertex based linear blend skinning with learned corrective blend shapes, has N = 10, 475 vertices and K = 54 joints, which include joints for the neck, jaw, eyeballs and fingers. SMPL-X is defined by a function M(θ, β, ψ), where θ is the pose parameters, β the shape parameters and ψ the facial expression parameters.
To install the model please follow the next steps in the specified order:
- To install from PyPi simply run:
pip install smplx[all]- Clone this repository and install it using the setup.py script:
git clone https://github.com/vchoutas/smplx
python setup.py installTo download the SMPL-X model go to this project website and register to get access to the downloads section.
To download the SMPL+H model go to this project website and register to get access to the downloads section.
To download the SMPL model go to this (male and female models) and this (gender neutral model) project website and register to get access to the downloads section.
The loader gives the option to use any of the SMPL-X, SMPL+H and SMPL models. Depending on the model you want to use, please follow the respective download instructions. To switch between SMPL, SMPL+H and SMPL-X just change the model_path or model_type parameters. For more details please check the docs of the model classes. Before using SMPL and SMPL+H you should follow the instructions in tools/README.md to remove the Chumpy objects from both model pkls, as well as merge the MANO parameters with SMPL+H.
You can either use the create function from body_models or directly call the constructor for the SMPL, SMPL+H and SMPL-X model. The path to the model can either be the path to the file with the parameters or a directory with the following structure:

├── SMPLX_NEUTRAL.npz
└── SMPLX_NEUTRAL.pklAfter installing the smplx package and downloading the model parameters you should be able to run the demo.py script to visualize the results. For this step you have to install the pyrender and trimesh packages.
python examples/demo.py --model-folder $SMPLX_FOLDER --plot-joints=True --gender="neutral"
