平面以glb格式导入 部分面片模型不显示 或者是在动画过程中显示异常 在某些特定角度可以看到。。 这是什么问题？

开发中，模拟器可以正常显示模型。上架后，只有手机端系统可以正常加载显示模型，windows端一直加载不出来是什么原因？

在xr-frame中，同样的glb模型，转动一下视角，部分Mesh就不可见了，非常影响体验。 尤其是带动画的模型，动画效果作用于Mesh之上，会使Mesh产生位移，而xr-frame的视锥体检测的是原始位置，导致会有情况看不到这些mesh。 （以上均是个人对xr-frame实现的猜测，实际情况还是需要微信大佬确认） 将模型动画停止后，转到视角会比较清晰的浮现。 [图片] [图片] 这个问题应该存在很久了，也有其他小伙伴报过，确实影响体验。 如果是视锥体问题，能否提供开关关闭此检测。 最后，我理解这种算法是为了提高性能，但是现在很多模型都会有这个问题，而在别的渲染器里都没有啥问题。

开发者工具上可以查看 ios无法识别组件 [图片]

https://developers.weixin.qq.com/miniprogram/dev/api/ai/visionkit/VKOCRAnchor.html 我看demo中的实时ocr注视掉了 [图片] 而且demo和文档好像也对不上 [图片] [图片] 我本地调用session.start 成功了，没有任何输出

        const session = wx.createVKSession({           track: {             face: { mode: 1 }           }         })         session.on('updateAnchors', anchors => {           session.update3DMode({ open3d: true })           anchors.forEach(anchor => {             console.log('anchor.points', anchor.points)             console.log('anchor.origin', anchor.origin)             console.log('anchor.size', anchor.size)             console.log('anchor.angle', anchor.angle)           })         })         // 当人脸从相机中离开时，会触发 removeAnchors 事件         session.on('removeAnchors', () => {           console.log('removeAnchors')         })         session.start(errno => {           if (errno) return         }) 摄像头实时模式，只有start会触发，返回的errno为null

[图片] 切换了很多基础库的版本仍然报错；项目结构和https://developers.weixin.qq.com/miniprogram/dev/framework/xr-frame/中的一样

ios微信更新到8.0.47后，xrframe的AR交互异常，以前能交互的全部都错位了点击不到，是bug？ [图片][图片][图片] 后面两张图的内容都无法点击，点到其他空白地方可能会触发到点击事件。

[图片] 截图中的墙，通过GLB格式导出后，导入到小程序xr-frame中，会显示一个黑不溜秋的东西，很难调节。 截图中的管子，通过点位数据导出，通过registerGeometry插入，会变成一个另类的东西。 [图片]【后面的那个白色就是那个管子】 附上插入代码【在xr-basic例子中插入】：       const xr = wx.getXrFrameSystem();
