问如何在THREE.js中修改gltf模型的材料？

EN

const modelPath = "your model path";
const texturePath = "your texture path"

const loader = new GLTFLoader();
const texture = new TextureLoader().load(texturePath);
loader.load( modelPath, function ( gltf ) {
    const model = gltf.scene;
    model.traverse((obj) => {
        if(obj instanceof Mesh){
            obj.material = new MeshBasicMaterial({map: texture})
            }
        }
    )

}, undefined, function ( error ) {
    console.error( error );
} );
