Worked on the google/filament repository to address a critical rendering issue affecting morph target animations in multi-instance scenes. Using C++ and 3D graphics programming expertise, implemented a targeted fix that isolates morph target buffers for each mesh instance, preventing the createInstance() function from overwriting shared data. This approach eliminated cross-instance rendering glitches and improved visual accuracy for applications relying on glTF morph animations. The solution was delivered with a focused code-path change to minimize risk and maintain workflow stability, and was directly linked to issue #9915 for traceability. Demonstrated careful engineering and attention to detail in game development contexts.
