var loader = new THREE.GLTFLoader(); loader.load(urlname,      function (gltf) {       model = gltf.scene;       scene.add(model);       createGUI(model, gltf.animations)     }, undefined, function (e) {       console.error(e);     }); threejs读取，调试基础包 2.26.0 微信版本：8.0.27 腾讯云COS服务器存储glb文件。 微信小程序发布上线后，第一次可以打开三维模型，显示正常，然后关闭小程序后，就不再显示，请问是什么原因造成的。

1.threejs-miniprogram，gltf-loader.js接口加载显示三维模型，加载的是glb格式的。 2.阿里云三维模型链接。 3.调试基础库2.26.0（ps，没有推送） 4.[图片] 可以清楚显示。 但是提交程序代码，审核通过，发布后，在手机上打开，我的三维模型没了！！！这。。。哪位大神知道怎么解决呢？
