hi..
in this video there is 2 diffrent renders of one simulation
the first shot was rendered with krakatoa (KCM color by vortecity)
the second shot was mesh rendered (15,000,000 poly every frame)
the "simulation" took 15-min per frame approx.
the "meshing" process took 8-min per frame approx.
the "krakatoa" rendering took 15-min per frame approx.
and the "vray" render took 16-min per frame approx.
hope you'll enjoy it :)
