Matthew,
I was poking around AppleARKitHitTestResult.h and AppleARKitHitTestResult.cpp, trying to see what it returns for the ARKitAnchor, and noticed this at the bottom of the header file for the declaration of the Anchor:
/**
* The anchor that the hit-test intersected.
*
* An anchor will only be provided for existing plane result types.
*/
UPROPERTY( BlueprintReadOnly, Category = "AppleARKitHitTestResult")
class UAppleARKitAnchor* Anchor = nullptr;
Pardon my potential complete ignorance, but isn’t this forcing the anchor to always return a null pointer?
