I tried following the instructions here https://developer.vive.com/resources/openxr/openxr-mobile/tutorials/unity/passthrough/ (and related pages) but LayerType.Underlay doesn't work for me (only shows black).
Using Unity 2021.3.2f1 I created two new projects (one Standard, one URP) and imported VIVE OpenXR Plugin - Android, VIVE OpenXR ToolKit - Android and VIVE OpenXR ToolKit Samples- Android. Then made a build of the sample scene PassthroughSample_Projection from the ToolKit Samples package. It works fine with Standard but the Underlay option still only shows black in URP.
Is there something I am missing?
