Where can i get skybox skins\models

[Mendel]

Hi, i was searching for skybox skins models, what ever, on hive.

BUT I FOUND NOTHING

i am searching for a space skybox skin, wich will have the ground painted too, the skybox wich the editor in defualt has are missing the ground (lower part) and it's just a black square...
if some one could direct me where i can get them i'll be gratful :]
