I worked as a "3D Generalist" on the EA Maxis "Sim City" team by helping update the existing building assets to futuristic building assets for their "Cities of Tomorrow" expansion pack. Other artists would create the sci-fi props to be used as add-ons, as well as the neon billboard signs. My job was mainly to simply use good judgement and hand place, scale, and animate where needed, for instance, the rotating vent fans, robot assembly arms, conveyer boxes, etc.)
