During January 2026, Mingda Yao enhanced the facebookresearch/momentum repository by introducing a new loadBlendShapes parameter to the character IO pipeline. This addition allows the CT API to load TLM files with blend shapes, expanding flexibility in character data handling while maintaining backward compatibility by defaulting to the previous behavior. The work, implemented in C++ with a focus on API design and game development principles, laid the foundation for improved character data pipelines and future downstream tooling integration. The changes were additive and non-breaking, reflecting careful engineering to support extensibility without disrupting existing workflows or introducing regressions.
