三.JS 3D模型已新增但不可見

我正在嘗試將 3D 模型新增到我的網站。我正在使用三個.js。我盡了一切努力，但無法使 3D 模型可見。在開發者工具的網路標籤中，我可以看到 MTL 和 OBJ 檔案已加​​載，但頁面只是空白。我嘗試了 3 個不同的 3D 模型，但同樣的問題仍然存在。我會提供任何幫助。 

<html>
<head>
    <title>3D Model</title>
    <style>
        html, body {
            margin: 0;
            background-color: white;
            overflow: hidden;
        }
    </style>
</head>
<body>

<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/87/three.min.js"></script>
<script src="/js/OrbitControls.js"></script>
<script src="/js/OBJLoader.js"></script>
<script src="/js/MTLLoader.js"></script>

<script>
    const scene = new THREE.Scene();
    const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    camera.position.set(0, 0, 5);
    camera.lookAt(scene.position);

    const renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    renderer.setClearColor(0xeeeeee); // Light gray background color
    document.body.appendChild(renderer.domElement);

    const light = new THREE.AmbientLight(0x404040);
    scene.add(light);

    const directionalLight = new THREE.DirectionalLight(0xffffff, 1);
    directionalLight.position.set(1, 1, 1).normalize();
    scene.add(directionalLight);

    const controls = new THREE.OrbitControls(camera, renderer.domElement);

    var MTLLoader = new THREE.MTLLoader();
    MTLLoader.setPath("/models/Silivri001/");
    MTLLoader.load("odm_textured_model_geo.mtl", function(material) {
        material.preload();

        // Set the path for the OBJLoader
        var OBJLoader = new THREE.OBJLoader();
        OBJLoader.setMaterials(material);
        OBJLoader.setPath("/models/Silivri001/"); // Set the correct path here

        OBJLoader.load("odm_textured_model_geo.obj", function(object) {
             object.position.set(0, -60, 0); // Adjust the values as needed
        object.scale.set(0.1, 0.1, 0.1)
            scene.add(object);
        });
    });

    function animate() {
        requestAnimationFrame(animate);
        renderer.render(scene, camera);
    }
    animate();

</script>
</body>

    透過將文件的 CDN 更改為更現代的 UNPKG CDN，從那裡加載所有 two.js 文件，並從您貼上在評論上的 URL 加載 3D 模型，我能夠成功加載文件。我還將物件的位置調整為 -5，將比例調整為 0.05。這是對我有用的程式碼：
