Jan 1, 2026January 2026: Key features delivered and stability improvements in Autodesk/maya-usd. Delivered USD export of animated light color attributes with test updates, boosting rendering fidelity and automation coverage. Improved Maya USD integration stability and maintainability through a code refactor (removed an unnecessary conditional) and a naming fix (StageCacheId to stageCacheId), reducing integration risk and future maintenance effort. Overall impact: stronger, more reliable USD export workflows and easier contributor onboarding. Technologies demonstrated: USD export pipeline, test automation, code refactoring, naming consistency, cross-module integration.
