Then simply place the red, green and blue pixels as you like. That means you need to subtract 1 pixel from the side of the heightmap and divide it through 64 pixels (= size of a small city). This bitmap needs to be named config.bmp and needs to be in proportional size to the heightmap. Therefore you create a new bitmap where each small city is of 1x1 red pixels, each medium city is of 2x2 green pixels and each large city is of 4x4 blue pixels. You will also need to set the size of each cities in your region. If you think your imported terrain ist too step, you can try to use "curves" in GIMP to flatten the heightmap when you are already in GIMP. So I did load it in GIMP, convert it from RGB to greyscale, saving and then it should work. But the file itself seems to get saved as RGB. For some reason, SC4 doesn't load the highmaps directly saved by TerraMaker, even as the colors are already in greyscale. Once you got a terrain you like, you have to save it as a 24bit greyscale bmp-file. So TerraMaker's standard sizes already fit to be used for the SC4 heightmap import. To get the needed size of the heightmap, you need to sum up all sizes of each citys in a row and to add 1 pixel.
TerraMaker supports heightmaps of 129x129, 257x257, 513x513, 1025x10x2049 pixels by standard.Įach small city has a size of 64圆4, each medium city a size of 128x128 pixels and each large city a size of 256x256 pixels in the terrain heightmap. For now, I did use TerraMaker to randomly generate a greyscale heightmap. 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.
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.
