Hi, I simply want the fog to increase when a player enters a region, and decrease when he leaves. Region is based on worldguard cuboid. Activator said: The fog you see in Spout is simply a method of making the render edge vanish smoothly into the distance; I doubt this could be applied in a cloud-like fashion. As a side thought, though, you could fake regional fog by forcing a short render distance when players enter a region and reverting when they leave. This would definitely require both Spout and Spoutcraft. Could any1 from dev team of Spout can make it possible ?
