So, what version do you recommend to start a new project based on the AR template?
Thanks in advance.

Still facing the black screen issue in 5.5.3. What version should I use now

24

Hey, I cant get it to work in any version of the engine. I’ve tried 5.1 all the way to 5.5 with no luck. Only thing to do right now is wait or try modifying the engine your self.

25

nope

I’m in 5.4 and it’s working, but you need to use OpenGL instead of Vulkan.

UE 5.4.2 works for me. UE 5.5.2 does not, and the upgrade to 5.5.3 didn’t touch this code so probably won’t work either.

As @stgdevm noted previously, you do have to disable Vulkan and enable OpenGL instead.

Hi there, I’ve just seen your reply. Im using OpenGL but it’s not building at all. Do you know of any other settings which could be causing the issue?

It depends on the error you get from the failed build

UE 5.5.4 was released yesterday. I just finished reviewing the commit list in GitHub, and I revisited UE-223981. As far as I can tell – and please correct me if I’ve overlooked it – this is not yet fixed in 5.5.4.

Still no luck.
Not corrected, it shows black screen over camera space

33

If the issue still hasn’t been fixed is there any other AR plugin available for us to use? does anyone know any other one?

34

Hi Victor, at the issue tracker the status has changed to “Won’t Fix”. Does this mean that UE is no longer suitable for developing AR games for Android?

Hi Vicktor.

I just wanted to drop in and see if you can give use any infomation on what is happening with Google AR Core and Unreal Engine. As others have mentioned the latest update didnt fix the camera Texture issues and there has been no mention of what we could do on our end.

When looking at the issue tracker it’s also now saying “Wont Fix” which is incredibly concerning.

We have been building a Google AR Core app for more than a year now which was backed by Epic Games through a Megagrant.

By the looks of this, it seams like Epic just said no more Google AR Core. If thats the case can you let us know as we will now have to rebuild what we have. Which we really dont want to do.

please, any help at all would be greatly apreciated.

We weren’t able to hotfix it for 5.5, and due to recent changes to OpenGL in Main we have provided support for Vulkan w. ARCore with this change: https://github.com/EpicGames/UnrealEngine/commit/f069cb8eb6bf09563e27f07b9e75638553325bc0

If you need to run on OpenGL we recommend you stay on 5.4, as moving forward we’ll be supporting ARCore w. Vulkan.

This is really good however with Vulkan its still not building and displaying a black screen. Is there any project settings or specific android version we need to be using to make sure this works?

38

thanks for the reply but the link you pasted doesn’t work. Are you saying the current version supports ar core with Vulkan now and there wn’t be black screen if we use it?

39

In Project Settings → Mobile, make sure OpenGL is disabled and Vulkan enabled.

You need to be logged in to Github with a connected Epic Games account to access the source code: https://www.unrealengine.com/en-US/ue-on-github

Yes, UE5/Main on GitHub. The change will also be in UE 5.6 when released later this year.
