glb文件材质丢失

[lsy]

按照官网教程加载glb文件，材质丢失

<script setup>

import { onMounted } from 'vue'

class RotateScript extends ComponentBase {
   update() {
    // update 生命周期，主循环每一帧执行
    this.object3D.rotationY += 1;
  }
}


let scene3D;

onMounted(() => {
  initEngine3D();
})

// 初始化引擎
const initEngine3D = async () => {
  let canvas = document.getElementById('canvas');

  await Engine3D.init({
    canvasConfig: { canvas }
  });

  // 创建根节点
  scene3D = new Scene3D();
  initCamera();
  // initLight();
  loadModel();
  render();
}

// 初始化相机
const initCamera = () => {
  // 新建摄像机实例
  let cameraObj = new Object3D();
  let camera = cameraObj.addComponent(Camera3D);
  // 根据窗口大小设置摄像机视角
  camera.perspective(60, window.innerWidth / window.innerHeight, 1, 5000.0);
  // 设置相机控制器
  let controller = camera.object3D.addComponent(HoverCameraController);
  controller.setCamera(0, 0, 15);
  // 添加相机节点
  scene3D.addChild(cameraObj);
}

// 初始化光照
const initLight = () => {
  // 新建光照
  let light = new Object3D();
  // 添加直接光组件
  let component = light.addComponent(DirectLight);
  // 调整光照参数
  light.rotationX = 45;
  light.rotationY = 30;
  component.lightColor = new Color(1.0, 0.6, 0.6, 1);
  component.intensity = 2;
  // 添加光照对象
  scene3D.addChild(light);
}

// 初始化对象
const initMesh = () => {
  // 新建对象
  const obj = new Object3D();
 
  // 为对象添 MeshRenderer
  let mr = obj.addComponent(MeshRenderer);
  // 设置几何体
  mr.geometry = new BoxGeometry(5, 5, 5);
  // 设置材质
  mr.material = new LitMaterial();
  // 旋转
  obj.addComponent(RotateScript);
  // 物体添加到场景中
  scene3D.addChild(obj);
}

// 加载模型
const loadModel = async () => {
  let data = await Engine3D.res.loadGltf('http://47.116.33.104:9000/syber-zen-test/LH4.glb');
  scene3D.addChild(data);
}

// 渲染
const render = () => {
  // 新建前向渲染业务
  let renderJob = new ForwardRenderJob(scene3D);
  // 开始渲染
  Engine3D.startRender(renderJob);
}

  <div style="width:100%;height:100%">
    <canvas id="canvas" width="1200" height="800" />

[说来有点可笑]

请问 你那边有解决吗？
