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?
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?
Hey, I'm also facing issues with passthrough. When play in editor everything works fine but when a package it for APK file and play it on my Quest, its just show passthrough mode like its appearing on front layer. Need help!!
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.
There was nothing in any Meta tutorial or documentation that mentions that you need to allow alpha through tonemapper in the Rendering > Post processing settings to be able to see objects in passthrough!
I spent hours trying to figure out why my objects appeared in the editor, but not in passthrough on my Quest 3 and this finally worked for me.
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
