Occlusion Portals
In order to create occlusion primitive which are openable and closable at runtime, Unity uses Occlusion Portals.
| Open | Indicates if the portal is open (scriptable) |
| Center | Sets the center of the Occlusion Area. By default this is 0,0,0 and is located in the center of the box. |
| Size | Defines the size of the Occlusion Area. |
