They must be 255, but the two values of the other colors can be used to have different kinds of the same color to get easier distinguishable cities of the same size next to each other. Here I have to correct my former posting, where I said the appropriate color values don't need to be 255. 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. 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.You will also need to set the size of each cities in your region. 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.

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.So TerraMaker's standard sizes already fit to be used for the SC4 heightmap import.Once you got a terrain you like, you have to save it as a 24bit greyscale bmp-file. TerraMaker supports heightmaps of 129x129, 257x257, 513x513, 1025x10x2049 pixels by standard.Each 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 to randomly generate a greyscale heightmap. I only see an All-Land or All-Water option in the game when trying to create a new region. Is that Terragen program on the same website? IronArcturus: In SimCity 4, is there a way to create a whole randomized region with different types terrain? 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.Also 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. Here's one as exapmle:As far as I can recall, some additions to this link:RGB values for the config.bmp don't have to be 255 only. It is also possible, to define the size of each city in a region with another rgb-map.So you can use 3rd party software to create randomized regions.Detailed descriptions can be found online. Seraphin84: Ingame there is no way for a randomized terrain.īut SC4 is able to import greyscale highmaps to create the Terrain from. In case you are not aware, the way that SC does its “regions” is through use of greyscale. Creating SimCity 4 real world maps from USGS data. Now, you can open a region to modify it.This software req. SC4 Region Maker 1.1With this software, you can create a region and especially the config.bmp file. It happens to be my own region, built off of the stock Maxisland region. Download a SimCity 4 region 5/8/05 - Wren Weburg After a long time since the game's release, a SimCity 4 region is finally here for download. But SC4 is able to import greyscale highmaps to create the Terrain from.Įver wish you could rezone real land as you can in SimCity? Here's the Onion's take on that, if you're in the mood for a chuckle. 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.
