Space ground/terrain ?

Space ground/terrain ?

Where can I find space ground/terrain like in the map Galactic Conquest ?
How can I import them ?
How can I use them ?

Nobody knows?

I don't know if this is the same as in that map but use the abyss tile to your tileset if you cant get the normal one to work use the wall tile or w\e to change your tileset add/remove/exchange tiles go into the advanced menu and go to tileset or something like that I hope this helps

[Note] Only flying units can go on the abyss tile.

and there's a good space texture at the skins section
