Here are the scripts for the training of our SDF and skinning models. In model_sdf.py and model_skinning.py, you can find how the loss terms are implemented and what values we use for weight balancing (check the function optimize_parameters()).
Note that the training of our skinnig model depends on kaolin-0.1.0, since we use it to convert the body mesh to an SDF for the purpose of collision penalization.
