You have to use Merge (Ctrl+R), not Export, to save your changes back to the existing map!.Merge (Ctrl+R or File -> Merge world.) will merge any changes you make back to the existing map. Import (Ctrl+I or File -> Import -> Existing Minecraft map.) will create a new WorldPainter world based on the landscape (terrain height and type and biome information, but no underground or above ground structures, trees, etc.) of an existing map. Having said that, WorldPainter does have limited support for making changes to existing maps, using the Import and Merge operations. WorldPainter is a map generator, not an editor! The basic idea is to use it for generating new maps which you then edit with other tools such as creative mode, WorldEdit, VoxelSniper or MCEdit. It will export the world directly to your Minecraft saves directory, after which it will appear in Minecraft under Singleplayer. Press Ctrl+E (⌘+E on a Mac) or use the File -> Export -> Export as Minecraft map. How do I play the world? How do I put the map I made in Minecraft?
