ARCore with Vulkan Support?

Hi,

I have just tested it and it seems Vulkan support for ARCore in Unreal 5.4 is not yet given. At least I get this when deploying to an Android device:

“LogGoogleARCore: Error: StartARCoreSessionRequest ignored - ARCore requires an OpenGL context, but we’re using Vulkan!”

When launching the game, there is no tracking and there is no camera feed, acts like a normal Android app.

And indeed I have enabled Vulkan because my app needs being graphically heavy.

I wonder which version of ARCore is implemented in Unreal 5.4 because Google has started supporting Vulkan for ARCore, see here: Render your AR app using Vulkan  |  ARCore  |  Google for Developers

Best wishes!

This matches my observations. I don’t believe Vulkan works with the SDK versions supported by UE 5.4.

We don’t support Vulkan for ARCore, and currently don’t have a timeline as to when we will.
