These instances are useful but putting them to use is odd. To me there is a lack of more useful information about this, especially a real example of it being used to move a player character around.

Also, going from air control back to ground control seems to be broken but who knows I could be doing it wrong. But at the same time the doc itself doesn’t really explain state switching.
Hi Daemon,
Thank you for the feedback. We know that the character controllers are a bit difficult to use right now - we’re actively working on the other tech needed to mitigate this. Once that’s done, we’ll update the documentation accordingly.
Nonetheless, if you think there’s an issue with going from the air controller back to the ground controller, please give us more information so we can look into it. Repro files + steps along with observed and expected behavior go a long way 
Thanks!
