, since some months ago I’m running the template with Unreal on Mac, and building it for both MacOS and iOS. My master thesis is focused on mixing VR and AR, meaning I am currently able to enter MultiMap01 with an Ad-Hoc AR Pawn, and see in AR what happens between VR Pawns. I plan to release my work (which is a modification of yours) to the public as Open Source as soon as I will be graduated. Of course I would love to share what I have done with you, and exchange Ideas. I’m sure I could learn a lot
