How enable Hololens 2 Spatial mapping occlusion in Unreal Engine

Question

Hello everyone!

I studied webinar working with unreal engine and hololens 2. This is a great lesson. And I understood how UxtTapToPlace works. But I can’t turn on the function of spatial mapping for occlusion of my Hologram. That is, so that the hologram is not visible behind real objects in my room.
I can set a solid mesh to the material for the spatial mesh, and then the holograms hide behind it, but when I hide this mesh, my hologram is always visible. Please help me!

Hello, Welcome to Microsoft Q&A,

You need to use an ARSessionConfig data asset for Spatial mapping occlusion, it is recommended to follow this step-by-step guide to add ARSessionConfig data asset first: Adding a session asset, and then, try the following steps to make the AR system render the mesh data as occlusion meshes:

1. Open the ARSessionConfig and expand the ARSettings > World Mapping section.
2. Check Use Mesh Data for Occlusion.
