I downloaded the fourth preview build for 4.20, and I can’t seem to find out how to enable IOS 12 support for Apple Arkit 2.0. Is there a hidden option or a checkbox that I’m missing, or is support just baked in “as is”? The main reason that I’m asking, is because I want to use the “shared world” multiplayer feature that Arkit 2.0 offers, so any advice or guidance that leads to that would be really appreciated.
did you find out?
