I don’t know how to do multiplayer development in VisionOS, and I hope to get it back.
VisionOS should support the same multiplayer technologies used for other platforms.
For example, in Hololens2, multiplayer space development through spatial anchors, can VisionOS do similar development?
If you mean multiplayer in the same (physical) room, then the best solution we’re aware of is to use fiducial markers (e.g., QR codes) and image tracking to align the spaces of each participant. That’s something we’re looking into supporting as a feature. The alternative without fiducial markers would be to use Apple’s ARWorldMap, but Apple does not support that (yet) on visionOS.
Thank you for your answer.
