Passthrough with Unreal Engine 5.1.1. underlay
Hello I try to setup a simple AR project that runs on PC with Oculus Link on a Quest Pro with a passthrough background and 3D objects over it. I have followed the official documentation https://developer.oculus.com/documentation/unreal/unreal-passthrough-overview/ and manage to have see a passthrough but it is always on top even if I configure it with "underlay" option.
What I am missing to make it works? What are the important settings to have in mind (for instance I have Enable alpha channel through tonemapper)? Does Forward/defered rendering have an issue on the result? DX11/D12?
Also is it necessary to use the Oculus fork of Unreal or a regular Unreal with MetaXR plugin is ok?

Does anybody manage to apply passthrough to a specific object with PCVR (like a window passthrough object in the CG world)?
the documentation is simple :
material with transluscent, unlit, opacity 1 and write only alpha true.
this doesnt work for me. any solution? - amx95Explorer
Hello everyone! I have a big trouble. I can't enable passthrough in any project except oculus fork passtrhough sample project. It's just don't want to work.
I use meta quest 2- CoolcatintownExplorer
Thanks amx95! This Solves my problem. For everyone who encountered the same situation, that setting pass is Project setting - Engine - Rendering - Postprocessing - Enable alpha channel support in post processing - Allow Through ToneMapper

Did you manage to solve the problem? I'm using Quest 2 and UE 5.2 with the MetaXR plugin. I just need to turn on the cameras at the touch of a button. I did everything as described in this article - https://developer.oculus.com/documentation/unreal/unreal-passthrough-tutorial/?locale=en_GB

And I forgot to say that I don’t package the project with a build, but work from the editor

I have experienced another bug with passthrough that appears randomly on build. Sometimes the passthrough appears very dark and red, it is very strange. Generally I close the oculus app and reboot the headset and it works again. I wanted to know if some of you experienced the same bug? Do you have an idea of what it could be?

I am having the same issue, the Passthrough Underlay with 3D Mesh work fine in the Oculus Fork Sample project, but when I try to the exact same documentation, only the Passthrough shows and no 3D Mesh.
Please help. - CoolcatintownExplorer
Did you solve the problem yet? I suddenly come across this situation. I have no idea what's going on.
