Max number of participants in the same room in Mesh?

marcoscarzello Mesh has 3 parts - you can use just avatars in your Teams meetings, you can use the View\Immersive space (3d) option in any regular Teams meeting to walk around in your avatar, and there's a separate Mesh app from the store - that's what we often call "standalone", since it's not part of Teams. The Mesh experience in Teams can only have 16, period. The standalone experience can have single room events (16 max) or the 200 max, divided into rooms of 16

>>They will always be divided in isolated rooms?

Correct

I have a Reactor talk where I walk through designing events, taking into account the 16 and 200 limits

(if you see docs from Microsoft that say 300 is the limit, please use the Feedback option on the doc page to let us know!)

hope that helps!
