I've spent a lot of time thinking how to implement various fog effects and everything is very complex, because of transparent objects which intersect each other and not drawed to depth, not trivial task.

yes this is a challenge.. my particle fog has a bad time interacting with water. Seams visible, cant resolve those... soft effect on the mesh helps a little, but doesn't remove it from water. Blurring edges would help a lot, but this just masks the problem, doesn't solve it.

I think that the second one looks the best, the 3rd and 4th looks way to random and unatural to me.
