Can sombody help me how could i make ground to my map plz help me.

Stop making new topics about this, you already have one topic about this question and that's more than than enough. This is even in the wrong forum, because it's not a bug or a glitch that you can't make ground.

1) Open the map maker
2) Make polys and put them side by side until they form something for your soldat to walk on
3) Hit compile and save the map
4) You have ground.

Edit: Make sure you place spawn points for your soldats to appear from.

do you not know how to make polygons?
well to do that, just hold ctrl and click in three places to form a triangle, that is a poly.
well, at least he picked a better section than, General Discusstions
