To create the basic layout of Koppollex, our medieval town-to-be, I am using the "Roleplaying City Map Generator", a free program available here: http://www.drachenzahn.de/city_map_g...city_maps.html This small application quickly creates the basic layout of hamlets, towns, and cities.
[NOTE: If you do not wish to use this application, you could alternatively create the map by hand directly into Photoshop; if so, skip this step and move on, below.]
Once you've opened the Generator, create a town map with any settings you prefer. One suggestion I have is to set the "Trees" toggle to zero (the trees the program generates do not gel well with the process we'll follow) [see the image, below]
After you create a map which intrigues you, click the “Export Selection as an Image”; in the screen that pops up…
• retain the 1 x 1 divide section
• select a larger file (I chose 2000 px in size, but this is really big, so be forewarned.)
• Choose “Colors”, and in that screen select colors for the major elements that will be easy to distinguish. These need not be the colors you will finally use, but I created a palette in the program that closely resembles the final colors I will use; I then saved this palette & now use it whenever exporting. (I also suggest setting all streets & street outlines to the same color, plus squares, parks, and the background set to another color.) [see image below] When you’re ready, save, etc., then click “Take This Time.”
• When ready, click “Create Image” and save it!
