The idea of this program is to convert a cell to a nif. Because I am lazy, it uses MGEs distant land meshes instead of this program reading the esp/esm itself. The bonus of doing it this way is you get the texture as well.
To get a good quailty texture, it is advised that you use 2048x2048 textures.

What is this useful for?
Possibly, you could use it for making interiors that act like exteriors with land meshes. This was always possible to do, but you had to use pre-made meshes.
Other things include landscape out of windows, if you used see-though windows in your house mod. You could have the inside landscape directly mirroring the outside landscape.

The nifs are:
4225 Vertices
8064 Triangles
They are exactly the size of one cell and have exactly the same detail as the default Morrowind landscape.
