ARKit has been updated in iOS 11.3 to include tracking images (similar to vuforia). Is there any chance we’ll see an update to support that in Unreal in the near future? There are other improvements as well, such as tracking walls… but fiducial tracking would be super to have, since there is no vuforia support for UE4.
We are also waiting for vertical plane detection to come for a project we are working on currently. On the other hand, I wouldn’t get very excited about ARKit’s image tracking. The quick tests I’ve done with Unity reveal that Apple’s image tracking tech is not near Vuforia’s at all (which I’ve used extensively). It really seems to be usable only as an image trigger rather than an accurate location anchor since the reported position is inaccurate and varies each time the image is detected.
