I have update my fog script from old A6 wdl to new A7 lite-c.
Wanted to share it with people.
It's made after silent hill 2, but eats away at your FPS, since it uses several function for each fog sprite.
At the time I had no trouble with it, since it was a big part of the gameplay and feeling.
You can use the code for free, and the dust particles i made (they were a 2 minute creation last night :P) as well.
