We are implementing a screenshot function with a Lens Flare in AR App on iOS.
We found a problem follows:
A Lens Flare is disabled at call Texture.ReadPixels on iOS!
Here is the screenshot and the simple unity project.
(See Attached File.)
if ProjectSettings > XR Setting > Vuforia AR was checked, This problem happen.
if that was Unchecked, This problem NOT happen.
Unity2017.4, Xcode 9.3, iOS 11.2 on iPhone X.
There are no problem on Unity Editor and Android.
Is there a solution?
