Worked on the godotengine/godot repository to deliver an animation pipeline performance improvement focused on TrackCache key uniqueness. Addressed cache collision issues by switching from hash-based IDs to using StringName pointer IDs as unique keys, and ensured stable identity by persisting StringName directly within Track. This technical approach reduced cache collisions and improved animation processing speed, resulting in smoother playback and lower CPU overhead during evaluation. The work was implemented in C++ and leveraged expertise in animation systems and game development. No regressions were observed, and the changes established a foundation for further performance tuning and scalability within the animation system.
