Adding details to a map ?

[sleepy1212]

so if i want to add all of these (fog,climate,etc)
i have to create or descompress a map... ?

yes, you'll need a bsp to add the weather to. if you extract you might as well get everything because if you're planning to add the weather the simplest way in sapien, you'll need a scenario to open.

in fact, unless you're modding you can't do anything to a .map file.
