Hi all. I’m sitting in the same boat as you guys and couldn’t agree more that the AR journey with Unreal is a constant up and down. Nevertheless I was able to fix most of the issues along the way but now I’m having a new one with AR Kit and 4.26. I wasn’t able to catch any big issues with 4.26 an AR Core though. Camera issues are gone, I was finally able to get better looking reflections on Android and the passthrough material setup works too. If anyone needs help on that regard, don’t hesitate to contact me. I’m also on the Unreal Slackers Discord going by the name “Thoeme”.
Regarding AR Kit and 4.26
First and foremost as far as I’m aware with 4.26 using AR Kit 3.0 support for older Apple devices is essentially gone. If I’m not mistaken this is a decision made by Apple. I’ve already created a dedicated forum post where I ask if someone at Epic could verify that. I really hope that I’m wrong on that one, because it would be an even more painful process if we would have to have two separate branches on each project. With current builds of our app using AR Kit and 4.26 they crash as soon as the AR session would start on older devices. With newer devices the AR session does indeed properly start and function. But I’ve experiencing strange rendering issues, which can best be described with an image:
So if any of you guys has any idea what the issue could be, I would be very happy to hear about that. Any suggestions are welcome.
