We are following the linked tutorial (https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unreal/unreal-hololens-camera?tabs=426) to try and render the HoloLens 2 PV camera in an Unreal application, but have been unsuccessful. We followed the tutorial exactly. What seems to be happening is that the image texture that is supposed to show up on the Blueprint plane in our blueprint never shows up. The plane resizes, then flashes Red Green Blue White rapidly a few times then the plane goes transparent. We know the plane is transparent and the plane is still in the scene because our hand rays interact with something transparent were the plane should be when trying to click on the plane in the HoloLens. We are not sure we are receiving the correct data from the ARTexture Object? Is there any way we can debug this or any extra steps that are not shown in the tutorial related to the material created?

We are using Unreal Engine 4.27.2 with the Microsoft OpenXR and OpenXR plugin enabled.
