Question

我们正在使用Unity编辑器以远程模式设计我们的hololens应用程序，以便将我们的全息图精细放置到房间中，然后在完成后将世界锚点附加到它们。在编辑器中一切正常（我们放置对象，我们改变它们的位置，我们在几天之后重新启动所有东西，我们所有的全息图都在正确的位置）。

但是当我们在设备上部署我们的应用程序时，我们所有的锚点都无法从锚点存储中加载。我们从编辑开始，商店包括我们的锚点。

所以，第一个问题是：在远程模式下使用编辑器时，锚存储在哪里？显然，不是在设备（hololens）上，而是在本地。如果这个假设是正确的，我们如何访问它们并可能在已部署的版本中使用它们？

第二个问题是，我们做错了吗？

这是一个可以重现问题的简短脚本。只需创建一个空对象，为其命名并附加脚本即可。应用程序启动时，会创建一个白色球体。您可以移动空并将其放在编辑器中，然后按“s”键保存锚点。在启动时，sript尝试从商店加载锚点。球体颜色告诉你它的状态（白色：球体解锁，绿色：锚点保存或从商店加载，红色：从商店加载的锚点没有成功，蓝色：在商店保存锚点没有成功）。从编辑器远程模式开始，保存您的锚点（锚点应该是绿色并且在下一次执行时处于相同位置）然后部署应用程序（您应该在相机前面看到红色球体，无论您在启动时查看方向）。

提前感谢您提供任何可能的帮助
