I have created an AR experience in Unity using Vuforia 7 and it's ground plane features. I have been able to place the object in the camera view where I want it, but as I move the iPad around, the object sometimes stays put and seems anchored in place, but other times it will drift and move along with me as I move, or it becomes shaky/jittery. Is there any way to improve this?
In addition, it looks like the object is not sitting flat or the perspective is wrong. If I look at horizontal lines in the background, the horizontal lines at the top of the object are not parallel to those lines but they should be.
The experience was created in Unity 2017.3.0p3 and is being run on an iPad Air 2 with iOS 11.2.
Thank you for your time.
