A software called Terragen should be one of them, as far as I can remember. Just be sure, they are - depending of their size - blue, red or green only and not mixed.Īlso there is software which can create random terrain and export them as greyscale picture. they can be less, so you can use that to make a kind of chess board for easier planing of city's with the same size, next to each others. RGB values for the config.bmp don't have to be 255 only. Here's one as exapmle: Īs far as I can recall, some additions to this link: So you can use 3rd party software to create randomized regions.ĭetailed descriptions can be found online. It is also possible, to define the size of each city in a region with another rgb-map. But SC4 is able to import greyscale highmaps to create the Terrain from. Ingame there is no way for a randomized terrain. IronArcturus: In SimCity 4, is there a way to create a whole randomized region with different types terrain? I only see an All-Land or All-Water option in the game when trying to create a new region.
