Paolo or anyone else, Question Time!

I'm working my usual monster outdoor scene and thought I'd try the ol' sun for a change.

Out of curiosity, I whipped out the google-fu while positioning things and did a little research on Lux's volumetric light, looking specifically for how to recreate a distance haze.

I didn't find much for how this might be done in Studio, but I did stumble over what I presume is the equivalent of the fog prop for Blender called 'dirty air'.

Going that route (the fog prop), is there a way to make this effect for a city? Or does Lux automatically calculate something similar for a hazy/dust-in-air look if one were to have a canyon-esque length of buildings?

I'm trying a trial render with the city in question - no fog prop - but it's a little slow going (as would be expected)...
