The main menu and editing toolbar contain quick shortcuts to most of the basic heightmap editor functionality. It is strongly recommended that your computer meet or exceed recommended specification to use this. The Heightmap Editor window (accessible from the World/Heightmap Editing pull down menu in the main menu bar, or from the globe icon on the main editor toolbar) is divided up into 3 main sections: Editing Toolbar, Brush Parameters, and Editing Window. Local, or high detail landscape editing functionality is still retained in the landscape editor.
With this program it is possible to create, sculpt, refine and even erode large sections of a landscape. The heightmap editor is a high level tool suitable for massive landscape terrain alteration but with experience and the proper settings it can achieve a fairly fine degree of detail. Rather than hand-editing landscape, which is time consuming, this tool allows you to paint the desired heights onto a 2D texture which the heightmap editor then converts to a 3D terrain mesh. The Heightmap Editor allows you to generate a height map for the landscape in a world space.
