I would like an SDK component that doesn't allow portals to be placed in certain areas while they can in others.
Maybe something like Team Fortress 2's func_nobuild, a trigger area that disallows Engineer buildings from being built inside the trigger https://developer.valvesoftware.com/wiki/Func_nobuild
This would allow world creators to limit what areas portals can be placed, rather than disabling them outright like we can currently. A use case example would be game worlds with a separate lobby from the game area, where users can place a portal in the lobby, but not in the game area where the portal could be used maliciously.
