Can I switch bounded scene to unbounded scene?

For example, I want to float multiple scene.
when player wants to watch to big screen or interact them, would like to switch unbounded scene.

You can switch between the 2 but hand tracking works only on unbounded mode. so there might be some tweaks you might want to do if you want to support the use of both bounded and unbounded mode

okay! thanks for advice😚
and is it possible to floating two scene?

We are working on multi-volume support (see roadmap here) so that, in the future, it will be possible to have two bounded volumes.

Thanks for anwser !
and is it true poly spatial does not support unity built-in cloth simulation?
