Customization - open the Tools tab, select one of the available editors and change the map in any desired way
Controlled generation - open the Tools tab, then click on Heightmap and select an Erase mode. Click on Template editor and create your own heightmap template. Apply the template to see the result. Don't forget to share good templates with the community!
Conversion - if you already have a map image and want to re-create it in a generator, open the Image converter (the button next to Template editor), load the image and fine-tune the conversion into a heightmap. Then edit the map using the Tools provided
