Hi Blauk,
Oh thanks!
I was playing with different hard sky texture ideas and only two feel good. Invisible or small clouds. Well, I'm not too good with PSP8 and clouds did appear as blobs... "Invisible it is!"
Great idea this wall grouping. The first build take same time to get wall ends match but thats it. Also longer walls could have little bit random shape, instead dead straight 1mile wall. There is one but. If terrain is not dead flat, then single long wall object has it advantage.
(edit)
Zip file contain also "StartG1.obg" file. It's a startgate object group (2 pole1+ start1). Save it to the Group folder.
