Worked on the playcanvas/engine repository to enhance the GLTF exporter, focusing on improving asset fidelity and material handling for 3D graphics workflows. Developed support for exporting ambient occlusion maps and second UV channels, enabling richer material textures and more complex material definitions within exported assets. The implementation, written in JavaScript, streamlined the asset pipeline by reducing the need for post-export adjustments and increasing compatibility with advanced material setups. Code changes were accompanied by clear documentation and code-quality improvements, ensuring maintainability and clarity. The work leveraged expertise in 3D graphics and GLTF exporting to deliver more realistic visuals in runtime environments.
