Worked on enhancing the GLTFLoader component in the mrdoob/three.js repository to improve its robustness when handling malformed or incomplete glTF files. Addressed a bug where missing skinning attributes could cause runtime errors by implementing validation checks that detect absent attributes before attempting to create a SkinnedMesh. If required data was missing, the loader now gracefully falls back to a standard Mesh and emits a warning, preventing crashes and broken rendering pipelines. This update, developed using JavaScript and leveraging expertise in 3D Graphics and GLTF, contributed to greater stability and reliability in asset loading workflows for Three.js projects.
