Hi all!
Am I supposed to get the** “real world north”** somehow using the “World alignment = Gravity and HEADING” in the AR session config file?
So far the “north” in world alignment is always fixed with the starting orientation of the device and it has nothing to do with the real north or heading.
Both ARCore and ARkit, the same conceptual lack of understading I have 
Many thanks!
(UE4.24)
Tested:
I got true north working on iOS (iphones and iPads). It was working straight from a box (currently using UE4.24).
However had a problem with Android.
And here’s a thing - for couple of versions TrueNorth also started to work in Android (in version 4.23) but stopped again.
Well that explains it! I had a same experience some time ago - it once worked, but now it doesn’t (android). I started to wonder if it ever worked. But hey many thanks, I’ll continue investigating it on iOS!
Thanks!
Have you managed to solve it?
It doesn’t matter how, but whenever I start the AR app I always get north aligned with the initial orientation of the device.
No, unfortunatelly. I haven’t tested it on 4.27 - but I would imagine you are using it?
Yes, version 4.27.2 and always get north aligned with the initial orientation of the device
