CS 1.6 Map Resource Maker

[mattisbogus]

Can someone please help me understand this.

I have been using C.B.G. Cs1.6 Map Resource Maker 1.5 to make .res files for some maps that I host on a dedicated server. I use it only when a map gives a user a problem, usually because he doesn't have a required .wad file.

But after really looking at a lot of maps, there are so many files that are required by the .bsp that I don't have to include in the .res file and the map still runs fine. Even after close inspection of some maps that didn't even come with models,sounds,sprites etc and are required by the .bsp these maps still run fine without them, but why?

Let me give you an example of a map. de_westwood. If you were to download de_westwood.bsp you could run and play the map fine, without any problems, and everything looks fine ingame. However, if you load that map into the resource maker, you will find so many files that are associated with that map, but why doesn't the .bsp need them to play? Let me show you what's in de_westwood.bsp

1. gfx/env/2desertbk.tga
2. gfx/env/2desertdn.tga
3. gfx/env/2desertft.tga
4. gfx/env/2desertlf.tga
5. gfx/env/2desertrt.tga
6. gfx/env/2desertup.tga
7. halflife.wad
8. itsitaly.wad
9. sound/ambience/guit1.wav
10. sound/nm_goodbadugly.wav

All of these files can be found in the de_westwood.bsp yet even if you don't have a single one, you can still play the map fine... now correct me if I'm wrong, I know some of those .wad files already come with CS, but what about everything else? I have numerous maps that are just like this.

Please I hope someone understands and can explain this to me.
