Importing existing Minecraft maps into WorldPainter

WorldPainter is a map generator, not an editor. However, it does have limited support for making changes to existing maps using the Import and Merge operations.

Importing an existing Minecraft map into WorldPainter

To import an existing Minecraft map into WorldPainter, use the keyboard shortcut Ctrl+I or 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 the existing map. It will not include any underground or above-ground structures, trees, etc.

Smoothing the seams

Once the map is imported, you can use the Smooth tool and other terrain tools to smooth the seams. Select the Read-only layer, choose a large and solid brush, and set the intensity to full. Paint the entire interior of the world with the Read-only layer to speed up the merge process. Be careful not to mark any chunks near the seams as read-only, as any edits in those chunks will be lost.

Merging the changes with the original map

To merge your changes back to the original map, use the keyboard shortcut Ctrl+R or go to File -> Merge World. Any chunks containing man-made blocks will be marked read-only by default, indicated by a black cross. Changes made to these chunks will not be saved during the merge process.

Fixing issues introduced by the merge

Changing the slope of the land during the merge process may cause issues with trees on the map. You will need to manually fix these issues by visiting the seams in Minecraft. For Minecraft 1.19 and later, Minecraft will automatically generate chunks adjacent to the generated part to smoothly connect with your terrain.

Merging changes with the original map

To merge changes with the original map in WorldPainter, follow these steps:

  • Import the existing Minecraft map into WorldPainter using Ctrl+I or File -> Import -> Existing Minecraft map. This will create a new WorldPainter world based on the landscape, terrain height, type, and biome information of the original map, excluding any underground or above-ground structures like trees.
  • Use the Smooth tool, terrain tools, or any other tool you prefer to merge and smooth the seams between the original map and your changes.
  • Select the Read-only layer and choose a large, solid brush. Set the intensity to full and paint the entire interior of the world with the Read-only layer. This will significantly speed up the merge process. Be cautious not to mark any chunks near the seams as read-only, as your edits in those areas will be lost.
  • Once you have made your desired changes and smoothed the seams, it's time to merge them with the original map. Use Ctrl+R or go to File -> Merge World. This will merge your changes back into the existing Minecraft map.
  • Note that changing the slope of the land during this process may cause issues with trees and other structures. You might need to manually fix these problems by visiting the seams again in Minecraft after the merge.
  • For Minecraft 1.19 and later versions, you don't need to worry about any special steps. Minecraft will automatically generate chunks adjacent to the generated part, ensuring a smooth connection with your terrain.

Remember, when importing an existing map, any chunks containing man-made blocks will be marked read-only by default, indicated by a black cross. These chunks are not merged during the merge process, and any changes made to them in the editor will not be saved. This protection is in place to safeguard man-made structures, as the merge process can be destructive, especially when altering terrain slopes.

Custom objects layer

WorldPainter supports four custom object formats:

  • The nbt format (as exported by Minecraft itself using Structure Blocks)
  • The bo2 and bo3 formats (as used by the Terrain Control mod). Note that the bo2 and bo3 support is limited; they can have various properties, but most of these are ignored by WorldPainter.
  • The schematic format (as used by MCEdit)
  • The schem format (as used by Sponge)

To add a custom object layer, click the + button on the Layers panel and choose "Add a custom object layer". Add one or more .nbt, .bo2, .bo3, .schematic or .schem files to the list using the + button. You can adjust the relative frequency of each object after adding it to the list.

You can paint with the custom objects layer just like with other layers. The higher the intensity, the denser the objects will be. WorldPainter will automatically rotate and mirror your objects randomly so they will look more varied. You can turn this setting off in the object options.

You can also select whether you want to place objects on the water surface (for example, for boats), underwater (for example, for sea temples), etc. You can put stuff completely underground by changing the offset to above the object.

There are a few websites where you can download collections of custom objects to use in WorldPainter, such as the Custom Tree Repository by Lentebriesje and the Batch .schem edit tool. You can also make objects yourself using MCEdit.

Adjusting water levels

You can adjust the water levels in World Painter in Minecraft by following these steps:

Firstly, import your map into WorldPainter using Ctrl+I or File -> Import -> Existing Minecraft map. You can then use the Smooth tool, terrain tools, and any other tool of your choice to make changes to the map.

To adjust the water level, open the Dimension Properties (Ctrl+P or Edit menu), go to the Theme tab, and adjust the number at the bottom of the screen. You can then choose to reset the water level across the entire world using the Global Operations tool or adjust the water level manually using the Flood and/or Sponge tools.

To reset the water across the world, open the Global Operations tool (Tools panel or Ctrl+G), select "reset all water or lava", and press Go. To do this manually, use the Flood tool to raise the level of bodies of water by left-clicking on them or lower them by right-clicking. Be careful not to interrupt the flooding operation, as this may cause tiles with incorrect water levels to be left behind.

You can also use the Sponge tool to reset the water level to the default in the area covered by the brush by right-clicking. Left-clicking the Sponge tool removes the water altogether.

It is important to note that changing the water level manually may have some downsides. For example, it will remove all lava and bodies of water that were above sea level, and it will flood valleys that are below sea level.

Additionally, if you want to avoid small water and lava lakes, you can set the world type to Superflat and use the Superflat preset to configure how Minecraft populates the world.

Editing on Windows 10

WorldPainter is an interactive map generator for Minecraft Java Edition. It allows users to ""paint" landscapes using tools similar to those found in regular paint programs. It is implemented in Java, so you need to have at least version 8 or 11 for running JavaScript scripts.

You can edit your Minecraft world in WorldPainter on Windows 10 by following these steps:

  • Import your existing Minecraft map into WorldPainter using Ctrl+I or File -> Import -> Existing Minecraft map. This will create a new WorldPainter world based on the landscape (terrain height and type, and biome information) of your existing map.
  • Use the Smooth tool, terrain tools, and any other tool of your choice to merge and smooth the seams.
  • Select the Read-only layer, choose a large and solid brush, and set the intensity to full. Paint the entire interior of the world with the Read-only layer to speed up the merge process. Be careful not to mark any chunks near the seams as read-only, as your edits in those chunks will be lost.
  • Merge the changes with the original map using Ctrl+R or File -> Merge World. This will save your changes back to the existing map.

Note that when importing an existing map, any chunks containing man-made blocks will be marked read-only by default. These chunks will not be merged during the merge process, and any changes made to them in the editor will not be saved. Additionally, changing the slope of the land may mess up any trees that were on it, so manual fixes may be needed after the merge.

It is also important to note that importing maps into WorldPainter is not its intended use case and can sometimes result in bugs. It is recommended to make backups of your maps and test the process before making any major changes.

Frequently asked questions

Yes, you can edit your Minecraft world in World Painter. You can import your map into World Painter using Ctrl+I or File -> Import -> Existing Minecraft map. After editing, you can merge the changes with the original map using Ctrl+R or File -> Merge World.

For placing complete objects, you can use a Custom Objects Layer. You will need a copy of the object you want to place in bo2, bo3, schematic, or nbt format. You can export the object from Minecraft using WorldEdit or MCEdit.

First, change the default water level setting by opening the Dimension Properties (Ctrl+P or Edit menu), going to the Theme tab, and adjusting the number at the bottom of the screen. Then, either reset the water level across the entire world using the Global Operations tool or adjust the water level manually using the Flood and/or Sponge tools.
