The Level Design team is responsible for creating the open world for World of Warcraft.
As Level designers we are directly responsible for the Zone layout and flow, creating Zone composition, creating individual Points of Interest and theme, terrain sculpting mountains/roads/hills/grasslands etc. terrain texture painting, work with the Art Team to develop prop kits, architecture kits, and then we use those pieces to build the Zone. We also work together on lighting and atmosphere to bring the world to life.
