About This File

This map began with a modelled picture of a dove, and was processed into an 8-bit 256 indexed grayscale. It was discovered that although a grayscale height-map could be 8-bit and 256 shades of gray, it must also be 'indexed' specifically as a grayscale image otherwise SC4 will simply render a flat region.  Thanks to @CorinaMarie for investigating the format and rendering the image into the initial dove-shaped island landscape.  From there, I developed the 'Dove Islands' region theme with a city layout (config.bmp).

Included in the zip-file is the preview image, install instructions (readme.txt), the Dove Islands region height-map, config.bmp, and region.ini file.  Also included is a file for the cloud background in the preview.  The 'region_bg_1-clouds.dat' may be placed in the Plugins folder where the game is installed. 

For more about creating grayscale heightmaps see:  C.O.R.I.M.A.P.S. - A Tutorial for SimCity 4

Install:

1. Place 'Dove Islands' folder in user account Documents/SimCity 4/ Regions folder.
2. Load SC4 and select 'Dove Islands' region
3. In region view press CNTRL+SHIFT+ALT+R and navigate to Grayscale Heightmap subfolder.
4. Select Dove_lslands_513x449.bmp
5. Wait for SC4 to render the map and create the city files.

How do I index this region as a grayscale image?

 

I didn't see any subfolder of the kind mentioned in the installation instructions.

The heightmap is already indexed as a grayscale, it will render the region map as seen in the center preview pic above.

The  folder named 'Grayscale Heightmap' is a subfolder of the one the install instruction is in: 'Dovetail__Map'

To make navigating easy, you could put the grayscale in the location SC4 opens up the window to find it.  For example, on my system SC4 looks in the root directory of Drive A: so that's where I store the grayscale images.

I found it, but it says the bitmap size is incorrect. Sorry about all my problems. I'm kind of new to this.

Did you copy the config.bmp from this download into the new region folder? That is the file that tells the region what size grayscale to expect.

And no worries for apologizing. We were all new to this at one time.

The grayscale map is 513 x 449.  The config.bmp is 8 x 7.

There's a thumbnail image in the 'Preview Images' folder called 'Dovetail_thumbnail.jpg'.  You could use that one as it *is* indexed as 256 grayscale in .jpg format, but the one intended to be used is the 'Dovetail_513x449.bmp' file in the 'Grayscale Heightmap' folder. 

If you're using Windows just put the 'Dovetail' folder in C:\Users\*Username*\Documents\SimCity 4\Regions\

Then start SC4 and load the 'Dovetail Region'.  Press CNTRL+SHIFT+ALT+R and navigate to C:\Users\*Username*\Downloads\Dovetail__Map\Grayscale Heightmap\Dovetail_513x449.bmp

If you keep getting a wrong size message tell me what size it asks for.

Thanks Cori, maybe I should use an installer option next time.   I won't even mention problems with SC4M files :)
