Exterior Cells

Exterior cells belong to a world space, and are part of that world space's landscape, which is basically a grid that extends infinitely in all directions. Each exterior cell is 4096 units by 4096 units or 192 feet by 192 feet or 58.5 meters by 58.5 meters. Each vertex in an exterior cell is 128 units apart - the same height roughly, as a human bi-ped, or about 6 feet.

Exterior Cells in the Render window

All exterior cells are automatically given a grid number that represents their X,Y coordinate starting from the center of the world space at coordinate 0,0. Cells to the right of 0,0 have a positive X coordinate. Cells above 0,0 have a positive Y coordinate. The cell coordinates of a selected object appear in the status bar at the very bottom of the editor.

Exterior cells have the following tab:

Renaming Cells

Exterior cells are given the name 'Wilderness' by default. To rename an exterior cell:

Left-click on the cell in the Cell View window. Pause. Left-click again, and type in a new name.

Note that you cannot rename a cell 'Wilderness' if you change it by accident. These 'wild edits' must be corrected manually using the Details button in the Data browser or by using an external application like FO3Edit.
