In 4.18 we have noticed that the new tracking system does not update the position of scene objects if the underlying tracked planes update. This causes some drift and loss of tracking in cases.
We see in the 4.18 ARKit plugin code there is some access to the Anchor data from the iOS SDK but that is not passed through to the engine side and is not used.
We have tried to pipe that through so we could update our attached scene info. But that is difficult due to the class structure and code without some significant changes.
Is there a timeline for integrating a system that will update the placement of scene objects once the tracked planes update?
