2.6.2 (2.7 beta 2)

To change the skymap, you need to make a cfg file. It work this way with all games using the Cube Engine.

When a map is loaded, the game load the map settings at running the file default_map_settings.cfg (of the config folder) then, if it exists, the config file of the map (a map file and its config file are in the same folder and have the same name except the config file ends with cfg instead of cgz). All ACR official maps have a config file, except ac_funhouse, ac_twintowers and acr_recreation.

P.S. : I downloaded your map and there are two problems :
* The first is its name. A map with one or several spaces in its name can't be loaded by the game. I needed rename it to open it.
* The second is the textures of the ceiling and the outer walls of the map. They are brick textures, not the sky special texture.

I just post on the armory an unglitched (but renamed) version of your map
