To start customization click on the arrow button to open the Options. Open _Customize_ tab and click on <kbd>Heightmap</kbd>. Click on <kbd>Clear all</kbd> button to remove the existing map and generate a new Voronoi diagram or <kbd>Roll back</kbd> to degrade a completed map (even a loaded one) to a heightmap. To start customization click on the arrow button to open the Menu. Open the _Tools_ tab and click on <kbd>Heightmap</kbd>.
Click on:
* the <kbd>Erase</kbd> button to remove everything except the Heightmap and edit the pure Heightmap.
* the <kbd>Keep</kbd> button to keep all data assigned to every cell and edit only the landmass without changing the coastline.
* the <kbd>Risk</kbd> button to keep all data assigned to every cell and edit the whole Heightmap*.
* the <kbd>Cancel</kbd> button to aboard changing the Heightmap.<br><br>
/*Like the button says the <kbd>Risk</kbd> option is risky and can cause a lot of trouble. Use this option only if you know what you are doing and maybe save before using it.

Once you are satisfied with the Heightmap, click on <kbd>Complete</kbd>. To minimize the failure risk the button activates only where there are at least some land cells. Once you are satisfied with the Heightmap, click on <kbd>Exit Customization</kbd>. To minimize the failure risk the button activates only where there are at least 200 land cells.
