it would be awesome to have a feature that allows for full multiplayer testing in editor, meaning that several game windows open and you can fully test the multiplayer experience like running it on multiple devices.
Also it would be great to be able to record the game in 4k resolution, like in AR kit 6.
Thanks for the feedback, I will make note of this and put it in as a feature request. Please note that we can’t guarantee when or if this feature will be available.
I wanted to update you that this is now possible with the integration of AR Foundation into ARDK 3. One such tool that our docs recommend for testing multiplayer is ParrelSync.
