So.. I don't really want to use tools if I don't have too, but I want to understand how the tools function. Like when I install for example the Nacht_Redesigned where does it actually store the contents to and am I able to just manually edit it's contents or is it all packed in a spec...

I haven't look too deeply into this not even sure if there's an open source version of this stuff.

I'm just curious as to how the maps work and what the game actually needs in order to load a new map. Disregarding tools completely. Like if we were to just start making files...
