I have implemented a 3D launcher model in glb format following the guide here. I am able to see the model in the Windows Mixed Reality home area, and the animations are functioning properly.

According to the documentation, the element uap6:SpatialBoundingBox is available for computers running Windows RS4 (1803) or later. I am running Windows 10 Pro version 1809, Visual Studio 2019, target platform version 10.0.10240.0, compiling a D3D project for ARM in Release.

However, no matter what values I provide for the SpatialBoundingBox element, the launcher's bounding box viewed in the home area does not seem to change. For example:

<uap6:SpatialBoundingBox Center=”1,-2,3” Extents=”1,2,3” />

vs

<uap6:SpatialBoundingBox Center=”0,2,0” Extents=”123,231,312” />

I have found on some occasions that the documentation is either ahead or behind the current state of the Hololens features, so I wanted to see if anyone else has been able to successfully implement a bounding box override.

是的，HoloLens 2 的 3D 应用启动器功能正在运行。请确保您的应用程序在 HoloLens 上针对的 Windows SDK 版本大于或等于10.0.17125，您当前的目标平台版本 10.0.10240.0 太低。在此处查看我们的文档

感谢您提出这一点，我们发现Extents字段设置在 HoloLens 上效果不佳，它应该旨在控制从边界框中心到其边缘的距离，沿每个轴。我们已通过内部渠道将此问题报告给产品团队，但无法保证 ETA。
