Stonemason's ruins? I think one of the key elements in the scene in the movie I am thinking about is the feeling conveyed by the office buildings in ruins and tossed cars: its obvious that it has been YEARS since any living soul called this area home - humanity has long since left this place.  In the storyline of the movie, you are told that most of the planet is this way.

Can you imagine going to downtown NewYork City - everything is covered with a light dusting of soot ... soot from not only the dirt being stirred up by daily wind & storm, but soot filled with decaying human remains that have been dried in the sun for almost 20 years? There's not a clear path for any good length - your echoing footsteps are the only sound? 

I can only imagine the system resources a scene like that would require to render. I guess the debris and burned out cars could be relatively low poly .. but the rest .. ouch.

Just enjoying the Vue. :0)
