Is there a cheap, but effective way in simulating weather conditions (ie. rain, snow, ect.) without physically putting "frozen rain" (as in the X City South route) or "acid rain" (as in the G route)?
I know that the background image can be changed, but replacing the .background image to an image of your choosing, which is relatively simple.
I also know that there's a fog command. Could someone explain how this works?
Any other methods?
