The cityscapes are indeed Moebius 87's Dystopia blocks (and are well worth the investment, no matter what version you use). Phoul loaded them into Poser, imported them into Infinite, then saved each one as a .vob file, to make it easier on Infinite's memory (saving as a vob destroys the link with Poser, which saves a lot a Poser has some issues with releasing memory). Then it is just a matter of creating the ecosystem terrain, and adjusting the settings so that the blocks are close, and at right angles to each other (or that you were very careful when importing, so that they have all the same alignment). Another tidbit is that all the lights have separate material enteries, so you could create a single cycle strobe effect on the lighting masts before you save the vob, and the animated material should be preserved, giving you night ready buildings.
