    The bug shows for any device with iOS15.x we tested, so this probably affects every user that upgrades iOS. Tested on iphone 12 Pro Max, mini ipad 4, iphone 6.

    Please vote to fix, getting artifacts when we render materials with over 0.5 smoothness on Mobile iOS games imapcts negatively a lot of gameplay.
