[Scene understanding example Vive openXr plugin - windows]

Thank you for the answer. A fresh project fix all the error. Now the "MeshingFeature" scene show the mesh of the room when i press the grip button on the controllers and spheres collides with the mesh.

Now how can I procede for the scene understanding? The readme says:

## How to use VIVE OpenXR SceneUnderstanding Unity Feature
For the available OpenXR SceneUnderstanding functions, please refer to **SceneUnderstanding.cs**.
1. Refer to **MeshingTeapotFeature.cs** which is modified from **Meshing Subsystem Feature** sample code provided by **OpenXR Plugin** for supplying a mesh from native code with OpenXR SceneUnderstanding functions.
2. Refer to **meshing_provider.cpp** under Assets\MeshingFeaturePlugin\Native~\ for generating mesh part.
3. Refer to **MeshingBehaviour.cs** for drawing mesh part.

I don't have a **SceneUnderstanding.cs** script. Can you suggest the steps we should do to see the scene understanding demo?

Thank you,

Marianna.

Hi, 

I am using Unity 2021.3.15f1, after following the steps for installing the vive openxr plugin and enabling the meshing subsystem and scene understaning openxr feature, If i press play this three errors appear:

Also everytime I exit from the playmode unity crashes.

Anyone is able to help me understanding what I am missing?
