World Painter
Anyone who has spent hours flattening hills block by block knows the pain of vanilla terraforming. World Painter changes that completely. This add-on recreates the layout, tools, and workflows of the famous standalone terrain editor directly inside Minecraft through a dedicated interface. Instead of switching between programs, you sculpt mountains, carve caves, and paint biomes without ever leaving your world.
What World Painter Actually Does
World Painter is an in-game world editing and terrain sculpting suite. It gives you a full brush engine, a layer system, and global operations that would normally take a separate desktop application to handle. The interface opens with Right Shift by default, and every control is configurable in the Controls menu.
Navigation feels familiar once you get going. You pan the map by dragging with the middle or right mouse button, zoom with Ctrl and the mouse wheel, and resize your brush with a simple scroll. Left-click applies or raises terrain, while right-click erases or lowers it.
The Sculpting Toolset
The core of the add-on is its sculpting suite, and it covers far more than basic raise and lower:
- Height tools for raising and lowering terrain
- Flatten, with Normal, Raise Only, and Lower Only modes
- Smooth for softening elevation differences
- Mountain and Pyramid for steep peaks and geometric shapes
- Erode for natural-looking weathering
- Spray Paint and Pencil for materials and biomes
- Fill for contiguous surface flood fills
- Biome Painter for painting biome IDs onto terrain columns
- Water, Lava, Sponge, and Flood Basin for liquids
- Select and Spawn Point for global operations
Brushes, Masks, and Filters
Brush shapes include Circle, Dome, Cone, Plateau, Mountain, Noise, Square, and Ring, plus custom grayscale .png brushes loaded from your worldpainter/brushes folder. You can fine-tune radius, intensity from 0 to 100 percent, and rotation angle.
Constraints keep your edits precise. Height constraints limit work to specific Y-levels with optional edge feathering. Slope constraints restrict application by surface angle. Block masking lets you paint Only On or Except On chosen block types, and the selection mask limits operations to inside or outside your active selection.
Layers, Palettes, and Procedural Generation
The terrain palette covers grass, dirt, sand, stone variants, clay, snow, and ice, with a custom block picker for anything else. Biome painting uses standard Minecraft biomes. Built-in layers handle Frost, Caves, Caverns, Chasms, Resources, and tree types including Deciduous, Pine, Swamp, and Jungle.
Custom layers extend this further. Objects spawn .schematic structures placed in your worldpainter/schematics folder, and custom ground cover lets you configure block state and surface thickness. For larger projects, procedural generation offers presets like Island, Hills, and Alpine with custom seed and size settings. Heightmap import and export work with grayscale PNG images, so you can bring terrain in from outside or send it back out. A multi-step undo and redo system protects your progress along the way.
Version Support and How to Install
World Painter for Minecraft supports modern Java Edition releases, including 1.20.x and 1.21.x, and runs through Fabric and NeoForge. Because it is a mod rather than a datapack, you will need a compatible loader installed before anything else.
If you want to download World Painter without wrestling with manual file placement, the foxygame.net launcher handles the whole process in a single click, and its catalog keeps World Painter updated automatically whenever a new build lands for your game version.
For manual setups, the process is straightforward:
- Install Fabric or NeoForge for your Minecraft version
- Place the World Painter .jar file into your mods folder
- Launch the game and open the interface with Right Shift
- Check the Controls menu if you want to rebind the key
Once loaded, everything runs inside your existing world. No external tools, no exporting, no waiting.
Final Thoughts
World Painter removes the biggest barrier to large-scale building in Minecraft: time. Whether you are shaping a single mountain or generating an entire continent from a heightmap, the toolset is deep enough for serious mapmakers and approachable enough for casual players. If terraforming has ever felt like a chore, this add-on is the fix.
