I don't know but when I installed it with Oscape it seams that it generated a map and when I enter a the world there is a whole new map if I open the map. There are some bugs like some things from Tamriel appear in the new custom world.
You'll still need Object and Tree LOD which can both be done with the CK itself. (Well, sort of. There are some issues with that, but nothing too rediculous)
How do can I make the LOD for objects and trees in the CK?
