Unreal passthrough over Quest Link

Hi there,

I am experimenting with Meta Quest 3 and passthrough. I can get it work if I push the project in to the headset however, if I use Quest Link I cannot get the passthrough layer working. Is this possible using quest link? 
it should be as if I use quest link and I go out of my boundaries I can see the passthrough showing off.

The cloned Github project doesn't actually allow you to change the XR API to Unreal Open XR.

Because all the OpenXR plugins are disabled in the project. maybe there is a conflict between the MetaXR and OpenXR

Disabling the OpenXR plugins in my project I managed to get Passthrough and VR Preview working.

Cool, that doesn't seem to work for me in UE5.3.2, but the Oculus UE5.3.0 works and I can also use the OpenXR support, all good. I've got other stuff to do so I'll leave this until UE3.4.

Take the headset off before pressing Play in editor. Once the preview window loads, then put the headset on. It took me way to long to figure this out.

Hi there,

I'm not really sure if this helps you, but I had the an issue where when I launched VR Preview the passthrough would work in headset, but I couldn't see any objects placed into the scene through my Quest 3 headset. I was able to fix this, though.

In Project Settings > Rendering > Postprocessing  change Enable Alpha Channel support to  "Allow Through Tonemapper."

No idea why this worked, and after you restart you have to compile shaders, but it worked for me using VR Preview and was able to see objects in my Quest 3 and it wasn't laggy. 

 

Live saver! That worked like a charm!

Interestingly, your suggestion of "let preview window load, then put headset on" fixed my crashes when using VR Preview when launching as client.

This made mine work!

I have the same issue. Native UE 5.3.2 with Meta XR plugin not working with passthrough. 
I want to give the Oculus UE5.3.0 version a try. But how/where can I download that?

You can't download a minor version (patch) of the engine from the marketplace. You cab download the latest 5.2 or 5.1 if you want to go back. But you can't go back from 5.3.2 to 5.3.1 for instance.

Those patches only fix bugs and don't add new features.
