PICO+Unity MR空间网格

官方链接：空间网格 | PICO 开发者平台

注意：该功能只能打包成APK在PICO 4 Ultra上真机运行，无法通过串流或PICO developer center在PC上运行。使用之前要开启视频透视。

在 Inspector 窗口中的 PXR_Manager (Script) 面板上，勾选 Spatial Mesh 选框。

新建一个空物体名为SpatialMesh，添加PXR_Spatial Mesh Manager组件（生成网格）、SeethroughManager代码（开启透视）、SpatialMesh代码（发射球）

PXR_Spatial Mesh Manager中的Mesh Prefab 至少需要包含 Mesh Filter 组件。如果想显示扫描到的网格，则还需包含 Mesh Renderer 组件。
