Maybe get a similar effect if you could use several individual
media statements, cobbled together in locations where the building interactions
are expected to take place. Not only that, but I suppose 'trace' would help
automate the locations.
Changing density (turbulence, scale, translate too?) those portions can
disappear and reappear as buildings are encountered.

I was too busy watching out for the approaching green cloud. Was only the lack
of AA that drew my attention to buildings. :)

Wish I had done more with media clouds by now but my impatience stopped me from
doing too much, and I'm not fond of complexities either. Time consuming and
there's always other things in life. ha ha
