Ive tried using the tuts but I cant figure the out so could someone please tell me how to do fog and ambient sound? Im an idiot so could you please spell it out?

setExpFog(density, red, green, blue, transition time)
Density is the density of the fog, it must be greater than 0 and less than 1, and typically less than .001. For example, .0002 means the fog gets .02%% more dense for every 1 unit of distance (about 1%% thicker every 50 units of distance).
Red, green, blue is the color of the fog. You can use following site for RGB color values, but you must divide them with 255.

setcullfog (near distance, far distance, red, green, blue, transition time )
Sets the amount of fog in the distance. The fog will increase linearly This fog pretty much cuts out all terrain and models etc.
For fog its really the best to mess around with values yourself and see, what changes and how.

ambientplay("soundaliasnamehere",fadetime)
ambientstop(fadetime)
Without fadetime, ambient track will start and end immediately, otherwise it fades in/out. Fadetime in seconds.

Info came from mod tools documentation.

Thanks man.

I had a problem, and it wont let me delete the message so....I edited it to this...123456789101112131415161718192021222324252627282930

I did what you said and I cant get it to work. I also tried to copy from other gsc files. the map just errors before it starts.

What you cant get to work and what does the error say?

sorry for the late reply. I think I got it now. :)
