Fog or Mist?
 

Hey!

I'd be really appreciative if someone perhaps knew a handy way to create fog/mist or know of any tutorials that touch on this?

you could probably get away with a simple (though large) cube or other primitive with a volume shader. look in the help files for more info on volume shaders and their options.

Ha ve a lookin the help files, theres some tutorials on creating fog in different ways
