Creating Cubic Activators
To create a cubic activator, select , then click on either an object or landscape. Dragging the mouse will scale the box in the X/Y plane until the mouse button is released, at which point the box can be scaled along the Z axis. A further mouse click finalizes the box and opens a dialog in which the activator's properties can be determined.

Creating Occlusion Planes
There are two ways in which occlusion planes can be joined. One occlusion plane can be spawned from another by grabbing the first plane's scale handle and holding down the 'alt' key while dragging. A second way is to use , which joins selected occlusion planes at their nearest edges. This button can also be used to break the connection between two selected occlusion planes.
Note that if you enter portal mode without a room selected, you can select portals (and only portals) but not create them.
Joining Portals to Rooms
One of a portal's room links is established when it is created. The other can be dynamically set or unset. Selecting a portal and a second room and pressing will establish a link between the two and align both properly with the portal's initial parent. After that, the portal can only be moved along the face separating the two rooms.
