Support for UE 5.2?

[Tim-Potratz]

Hi, just what the title says.
Many thanks in advance.

[james-yoo]

I also want to use this plugin in UE5.2!

Same, i updated the string to 5.2 in plugin but getting and error Engine\Plugins\Runtime\OpenXR\Source\OpenXRHMD\Public\OpenXRCore.h(15): error C2065: 'XR_ERROR_SPACE_COMPONENT_NOT_SUPPORTED_FB': undeclared identifier

Any news on this please? Also 5.3 is just released, can we get an easy way to upgrade?

Hoping for UE 5.3 as there's lots of stereo rendering fixes/improvements. We'll have to hope!

Unfortunately, Hololens/Hololens2 has been removed from the supported XR devices since UE5.3.

Bump... 5.2, 5.3, and/or 5.4 (soon)? These headsets are quickly going to turn into very very expensive paperweights without this and UXTools!

Sadly it appears to become exactly that.

This is quite disappointing if this really does mean the end of improvement/maintenance of all these tools. UE is getting so good just when MSFT gives up! SMH... The future was looking so beautiful...

I've updated it for 5.2 if someone needs it https://github.com/Olli1080/Microsoft-OpenXR-Unreal/tree/5.2_plugin
Beware that you have to build the engine from source since there is a bug in UE 5.2 preventing you from chosing any installed toolset for HoloLens builds.

The patch is how i got rid of the bug.
ue5_2_1_hololens.patch

Nice, and thanks! Will try it out, so the release version of source 5.2 should work with it?
I assume after compilation choosing the packaging option from Editor will also work?

[Renbry]

You just made my day! Wohoo!

It seems to enable on a vanilla UE 5.2. I'm only interested in Remote Rendering so perhaps the advice to build from source only applies to doing HL2 compatible builds (?)

[Olli1080]

@bvaibhav1 yes the patch is for the release branch 5.2(.1) of the unreal engine source repo.
Choosing packaging options did work for me, pls tell me if you encounter any error.

@Renbry Yes the patch only applies to HL2 packaging from the engine.

I may have got my hopes up...

"Open XR Holographic Remoting" (in Project Settings\Platforms ) doesn't seem to connect to the Hololens like usual, nor does the project have "VR Preview" as an option. Somehow the plugin is loaded succesfully but doesn't function in the way it did in UE 5.1 (For the purpose of remote-rendering)

Dang!!

I managed to make the plugin to work in 5.3 !
But it will only work by streaming from the PC. (as the support for the hololens plateform has been removed from the engine)

I've removed the parts that don't compile (like the ability to render the camera in a texture, which could probably be fixed.. I didn't do more researches because I don't need this feature but it doesn't look it could be a problem)

It's not that hard to port and it works pretty well so far. But keep in mind you will never be able to build an embeded app anymore in 5.3.

[Renbry]

I'd LOVE to just stream to the device. We use the 3090/4090 to render the nanite/heavy Unreal features and have lamented the 5.1-only official plugin. I'd love to try this 5.3 version!
