Worked on the playcanvas/engine repository to enhance the GSplatOctreeResource system by implementing manifest data caching and improving memory management. Focused on enabling consumers to access custom manifest fields without repeated network requests, the solution retained parsed manifest data for efficient reuse. Memory footprint was reduced by explicitly nulling resource data after destruction and dropping unnecessary references once consumed, ensuring safer resource lifecycle management and preventing leaks. All changes were made with careful attention to backward compatibility, requiring no updates from existing users. The work utilized JavaScript and front end development skills, emphasizing robust resource management and internal data handling practices.
