Extensions missing in kit-xr-samples and assets problems in "How to Build a Native OpenUSD XR Application" Course

[l.kamigauti]

Hello!

As the title says, the extension omni.kit.xr.scene_view.core which is a dependency in GitHub - NVIDIA-Omniverse/kit-xr-samples is missing from the registries default, sdk and community.

For the course, omni.kit.xr.example.usd_scene_ui’s dependency omni.kit.xr.sceneview_utils with version=‘^105.1.0-217’ do not exist in the registries as well (the latest release is omni.kit.xr.sceneview_utils-105.1.0-192+105.1)

How could I circumvent this hindrances? I need to learn how to make UIs for VR.

(Also, for the course, at one point, loading a factory scene is needed, but there is a lot of errors initially due the lack of the hydra, so I added the “omni.hydra.pxr” = {} dependency in my kit file, which helped, however, the materials and illumination of the scene are bugged, but not preventing me to following that part of the course).

It depends on the version of Kit you are using when using these extensions. If you are using the latest (Kit 108.0 as of this post), then the extension omni.kit.xr.sceneview_utils no longer exists and was replaced with omni.kit.scene_view.xr_utils. Maybe the .core extension was also renamed/replaced.

The Kit-XR Samples GitHub repo shows it was set up for Kit 106. You would either need to use Kit 106 or do the necessary changes to the example extensions to work with Kit 108 (or whatever version you are using). I hope that helps!

I am verifying this information. It may be that we have not yet published the XR / VR extensions for kit 108 yet.
