Okay, it' s time to report the current situation:
@Dmxj and @Ctrz It is possible to move/replace every part of a map. I mean the spawners, constructible stuff, cp, doors etc. (just like Minecraft or Lego). So everything is possible I moved the axis spawners from cp into the building and it works fine. I followed the same method with constructible barrier... works fine. However it is really hard to set textures and models back since I have to convert the map twice... yes TWICE. The (mapname).pk3 file contains a (mapname).bsp file: this is the map that can be loaded only in game. The .bsp file is a converted .map file. Map file can be loaded in map editor software, but can't be loaded in game. When I convert .bsp into .map file, a lot of details change or get lost. Recovery takes a lot of time, since Battery is a large, terrain map. The author of the edited version didn't place the .map file in the .pk3 file in 2008. That means I mustn't edit his/her map without permissions. (Yeah converting is quite illegal and disrespectful, if the map will be used on a server. Adding glass roof/editing the original version of the basic maps is allowed ofc.). So these are the options:
- keep this version of the map or replace with an other one
- modify the standard map (it doesn't take a lot of time, and you can suggest your ideas).
The decision is up to you, but note that: you'll never find a map wich is good/acceptable for every player
