The first technique is using roads that are a combination of decal surface and mesh curbs in order to reduce polygon count and increase the detail level of street markings. The initial post provided an artist's rendition of the map layout, showcased several WIP areas of the highways and motorsports facility, and explained the two new map-making techniques that WCUSA was originally designed to test the feasibility of. West Coast USA was officially revealed to the community on Jby B25Mitch, the developer primarily responsible for its construction.
This map is 4 square kilometres and features a city, highways, mountains, and a Motorsports facility that contains a racetrack with multiple routes, two separate dirt tracks, and a drift course in the parking lot. Los Angeles may have been an inspiration for the map as well. The metro area is similar to that of San Francisco and the map itself has similar geography to Oakland, California, what with the mountains to the east, a body of water to the west with a bridge going over it, and a north to south freeway running along that body of water.
West Coast, USA is based on parts of California including the San Francisco Bay Area.
