How to make Fade levels?

[Bugweiser]

looking at the toolset something that makes me curious is how did Bioware make the fade levels. They feature multiple individual terrain meshes representing the individual islands. Whereas afaik you can only make one big one. Did Bioware somehow export the level into 3dsmax and import it back or is there some function in the editor I'm not aware of where you can delete vertices in the terrain mesh?

Nevermind I figured it out. Upon closer inspection of the levels all Bioware did was stretch a large water mesh onto the bottom to mask the individual "islands" of the fade. The bottom of the terrain mesh was still there all along just painted black
