WorldPainter is a free tool for Minecraft builders that allows users to create custom maps and terrain. It offers a different way to create Minecraft worlds, including the ability to make huge mountains in a short time. Users can import and edit existing Minecraft maps in WorldPainter by using the Import function (Ctrl+I or File -> Import -> Existing Minecraft map...). However, it's important to note that WorldPainter only supports limited changes to existing maps, and certain areas, such as chunks containing man-made blocks, may be marked as read-only and cannot be edited. To save changes back to the existing map, users must use the Merge function (Ctrl+R or File -> Merge world...). This guide will provide an overview of how to load and edit a save in WorldPainter, covering topics such as importing maps, merging changes, and the limitations of editing existing maps.

What You'll Learn

Importing an existing Minecraft map
WorldPainter is a tool for Minecraft builders that allows you to create your own maps. It can import Minecraft maps and, after editing, merge the result with the existing map.
To import an existing Minecraft map, go to File -> Import -> Existing Minecraft map. This will create a new WorldPainter world based on the landscape (terrain height and type, and biome information) of an existing map. However, it will not include any underground or above-ground structures, trees, etc.
You can also use the \"bedrock wall\" option on the Export screen to make it hard to leave your world. However, this will create an ugly wall around your world, which you can combine with a border so that it's not visible from the shores of your world.
When importing an existing map, any chunks containing man-made blocks will be marked read-only, and these chunks will not be merged during the merge process. You can still edit them, but your changes won't be saved.
It's also worth noting that you can only import chunks that have already been loaded. This means that you will only see the spawn area, and the border will not be straight.
If you want to merge with an existing Minecraft map, you can select the chunks you want to merge and the location is based on coordinates. You can change the coordinates by shifting the map.
One user recommends not trying to merge, and instead making a new WorldPainter map, then using WorldEdit to copy/paste a huge schematic of your existing map into the new WorldPainter map. They note that merging with WorldPainter will be rough around the edges, and you have to make sure that any original terrain is not touched by WorldPainter, so only new chunks will be added.

Merging changes with an existing map
WorldPainter does support making changes to existing maps using the Import and Merge operations. To import an existing Minecraft map, go to File -> Import -> Existing Minecraft map, or use the Ctrl+I shortcut. This will create a new WorldPainter world based on the landscape (terrain height, biome information, etc.) of the existing map.
Once you've made your desired changes, you can merge them with the original map by going to File -> Merge world, or by using the Ctrl+R shortcut. It's important to note that you must use the Merge function, not Export, to save your changes to the existing map. Additionally, any chunks containing man-made blocks will be marked read-only and won't be merged during the process. You can still edit these chunks in the WorldPainter editor, but the changes won't be saved.
When merging with an existing Minecraft map, you can select specific chunks to merge and choose the location based on coordinates. It's recommended to ensure that any original terrain is not modified by WorldPainter, as it will add chunk borders. Instead, only add new chunks to the existing map.
Before attempting to merge, it's suggested to create a new WorldPainter map and use WorldEdit to copy and paste a schematic of your existing map into the new one. While this may result in rough edges, it avoids potential issues with merging directly into the original map. Remember to always make backups of your maps before attempting any significant changes.

Choosing the directory
When choosing a directory for your save file, consider the following:
Firstly, it is essential to understand that specific save file formats are required by World Painter to function correctly. Ensure that your save file aligns with the accepted formats, including schematic files (.schematic), Minecraft save files (.minecraft), and World Painter's proprietary format (.wptypes).
Secondly, opt for a directory that is easily accessible and well-organized. Consider creating a dedicated folder specifically for your World Painter projects, clearly labeled and separated from other Minecraft-related folders. This approach enhances save file management and makes locating specific worlds more straightforward. Creating subfolders within this directory for different projects can further streamline the process of identifying the desired save file.
Additionally, pay attention to the available storage space in your chosen directory. The size of World Painter save files can vary depending on the scope and intricacy of your world. If large-scale projects are anticipated, ensure that your directory has sufficient space to accommodate these files.
When deciding on the directory, take into account any unique requirements or preferences you may have. For instance, if collaboration or online sharing is on the agenda, consider selecting a directory that facilitates easy access and sharing, such as a folder synchronized with cloud storage. This simplifies the process of exchanging save files with others.
Lastly, remember that you are not bound to a single directory choice. If you find yourself unsure about the optimal location or if your needs change, you can always move your save files to a different directory. World Painter allows for flexibility in this regard, enabling you to browse and select new folders as needed.

- Choose the topography of your world. You can select a flat or hilly world. If you want to create an island, for example, you would choose "hilly".
- Set the "Level" or Y value. This refers to the F3 value, which you can leave at its default setting.
- Set the Water level. If creating an island, the recommended setting is ~77.
- Choose the different underground materials for your world.
- Decide on the border of your world. You can opt for an infinite ocean, the void, or a bedrock wall.
- Set the seed and chest of goodies. The chest of goodies is an OP chest with diamonds, emeralds, and other goodies that will be on the spawn point.
- Set the other settings of your Minecraft world, such as difficulty and survival mode.
- Once you have made all your selections, click "Export" and wait for your world to be generated.
It is important to note that WorldPainter has limited support for making changes to existing maps. However, you can use the Import and Merge operations to create a new WorldPainter world based on the landscape of an existing map or to merge any changes back to the existing map.

Exporting to Minecraft
WorldPainter is a tool for Minecraft builders that allows you to create your own maps. You can choose the name of your world, the different underground materials, and the border of your world. You can also set the seed, which is the "chest of goodies", containing diamonds, emeralds, etc. This chest will be on the spawn point.
To export your world to Minecraft, click "File" on the top left of your screen, then click "New World". Name your world, and leave the "Map Format" as the most stable version. Set the dimensions of your world, and choose whether you want a flat or hilly world. You can then set the "Level" (the Y value) and the water level. Once you have made your selections, click "Export" and wait for the process to finish.
It is important to note that WorldPainter can only import and merge changes to existing Minecraft maps, rather than directly editing them. To import an existing Minecraft map, go to "File -> Import -> Existing Minecraft map...". After editing the world, you can merge the result with the existing map by going to "File -> Merge with Minecraft map...".
You can also use the Import/Merge functions to smooth the seams of your world. First, load your map into Minecraft and fly along all the edges, forcing Minecraft to generate all the chunks around the edges. Then, import the map into WorldPainter and use the Smooth tool, terrain tools, and any other tool of your choice to merge and smooth the seams.
