No idea if that works. Hope it does. An alternate would be pwEffect and creating a primiive plane with a wavey displacement map then playing around witth the effects until you get the look you want. I did once in a render a long time ago.
Ok - it seems to work in DS4.5 just fine - there are many options to adjust the planes & the levels of fog (so many options) - this is a very quick & not very good render that I threw together to show the tool in DS4.5 With adjustments you could probably get the look you are after hope that helps
*The Gorilla is between several vertical planes - that is why the effect looks a little odd - with adjustments that cut through effect could be reduced, but I wanted to get an answer to you fast
You already have a “tool” installed for this, it’s called UberVolume and you’ll find it under shader presets, just create a primitive to cover the area you want the fog to be in and apply the base shader or one of the presets to it, do a spot render and tweek the settings till your happy.
