Contributed to Autodesk/maya-usd by developing and refining features for 3D animation pipelines, focusing on MaterialX shader export, light and camera data handling, and robust cross-platform build systems. Leveraged C++, Python, and the Maya API to implement MaterialX surface shader writing, animated light spline export, and metadata propagation for LookdevX workflows. Enhanced performance and maintainability through targeted refactoring, improved error reporting, and expanded test coverage. Addressed complex issues in file I/O, transformation matrices, and USD integration, delivering fixes for build compatibility and data correctness. The work enabled higher fidelity exports, streamlined animation workflows, and more reliable asset interchange across platforms.

Feb 1, 2026February 2026 — Autodesk/maya-usd: Load Rules Performance and Readability Enhancements delivered, consolidating and refactoring load rule handling to boost performance and maintainability. The update includes optimized updates during renaming and child insertion, clarified lambda usage in loadRules.cpp, removal of non-value-added comments, and safeguards to prevent unnecessary re-compositions during duplication/removal of rules. These changes reduce latency in the USD load pipeline, improve code readability, and lower risk of regressions during rule edits.

Jun 1, 2025June 2025 monthly summary for Autodesk/maya-usd: Focused on stabilizing exporters, improving lighting and camera data handling, and hardening builds across platforms. Key features delivered include Light Spline Export Improvements and Light Attribute Import Support (commit 49158c3a5ed144adef3ef34c276bbee9089ca724); Camera Attributes Export When Not Animated (commit 7ccff6713692f6b4d25245c637a3c0f7d8bc4c85); and MaterialX Export Relative Texture Paths (commit 7bf5fd8caffc49dc2afa2963da340291be0747e4). Major bugs fixed span build/compatibility, crash resilience, and data correctness, including Build and Angle Conversion Fixes for Older Versions, Crash: Input Might Not Be Part of a Node, Light Bug Fix, and VS/Clang/Linux build fixes. Additional stability improvements address Animated Export Transform for versions below 2505, Rotation Order correctness for USD (and import tests), and comprehensive tangents/transform handling fixes, all accompanied by targeted tests. RotateAxis enhancements and broader build/test minor fixes further reduce risk in production pipelines. Overall, these changes reduce exporter crashes and data inconsistencies while expanding path and attribute handling, enabling more reliable USD exports for animation pipelines and asset hosting.
