Prevent players from dropping VRChat portals in the middle of your dancefloor.

But still allow your staff members to open portals to a new instance of your VRChat event.

Players are allowed to drop portals, but ONLY in specified areas.
Players who clicked the "Allow Portal" button, can drop portals everywhere (for staff).

ver. 2 - Changelog:

• Add the whole system with a few simple clicks. No manual setup required!
• Static and dynamic whitelists.
• Editor gizmos added
• Screenspace indicators when entering and exiting portal zones
