in the options tab of the same window turn of render landscape and backface culling.
in the image tab set the sky size to what ever you want it i use 512 * 512.back in the main window set detail to high.
open word pad and add the following code:

;Notes:
;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
;The 3GSE engine will expect the images to be
;in the order of South, East, North, West, Down, Up.
;
;Set your render resolution to 512x512 pixels if you have the unregistered terragen.

;This will actually wind up as east in WED skycube.
;To make the lens flare line up with the sun in the terragen file, you would add
;180 degrees to the sun position. The altitude of the sun remains the same.
;Example: Terragen has the sun at -60 degrees. In WED you would assign it 60 degrees.

save as makesky.tgs
back in the terragen program select execute script and chose makesky.tgs
then open your image prgram and make a file with the same height and 6 times the width of you image, (i suggest ifranview) then paste the images in in the order of 1 2 3 4 5(should be blank) 6 save and your done!
