Question

Solution to stream Passthrough View via Quest Link

Hi All, 

I'm working in an Unity project with a passthrough view enable for visualization purpose and I'm trying to find a solution to stream my Quest 3 view onto a TV or any display.

Previously, I used the Quest Link from Unity to Quest 3 and used the iPad to cast my Quest 3 view onto it and connect it to an TV via HDMI. However, this doesn't seem like the best solution as I experienced some issued with it while running Quest Link.

I thought about using some sort of dongle (Thunderbolt?) to connect it to Quest Link and have an HDMI out but I'm not sure if it works in the first place.

To summarize, I would like to stream my passthrough view onto a TV WHILE using Quest Link from Unity (building the app onto quest 3 is not desireable).

Cheers.

Did passthrough work over link cable? I keep thinking I was having problems with it, and as of this last update it's telling me it's not enabled. I came here hoping to find out why. 

But maybe it never worked.

As of the latest Meta Quest Link update, the "Beta" tab which has the "Passthrough over link" is gone so I'm not sure what's going on there.

But I can say that it's been working for us before that Meta Quest Link update in our Unity project

okay good, I thought it was working here, too, and I just checked some old videos I'd made. Some I definitely had it working at some point. 

But when the v83 update on link dropped without a v83 SDK, I lost everything that worked over OpenXR. 

I hope they figure this out soon.
