Now simply paint your map into existence in the main view. In the drop down menu below 'Terrain' you'll be able to select anything from grassland to mountains. First, set the size and shape of your brush with the top two options, and then make sure the 'Terrain' pip is checked in the list of options below. The fastest way to create your world is using the 'paint' tab. At the top right you'll notice a series of tabs under the heading 'Map Editor Tools'. You can raise mountains, throw down jungles and sew rivers into the terrain by simply painting tiles onto the ocean. The first thing we need to do now is create some terrain.
On this screen you'll be able to fine tune every aspect of your map.
