WorldPainter

What WorldPainter is

WorldPainter is a free, open-source interactive map generator for Minecraft Java Edition. Users can sculpt terrain and paint materials and landscape features such as trees, snow, and ice onto maps, then export a generated world directly to the Minecraft saves directory. It is primarily intended for map creation; support for modifying existing maps is limited to Import and Merge operations. The software supports custom mod blocks, using fully qualified names for Minecraft 1.15 and later and numeric IDs for versions 1.12 and earlier. Custom object layers can load BO2, BO3, schematic, or NBT objects. WorldPainter does not make Minecraft structures itself, but can direct Minecraft to generate them during population. It runs on Windows, macOS, and Linux and requires Java 17 or later. The download page provides SHA256 checksums for installer files. The maker points users to the official subreddit for support and says a proper user manual is not yet available, while linking documentation for controls, FAQs, plugins, and scripting. It cannot customize biomes while leaving Minecraft to generate all land according to those biomes.

Who it suits

WorldPainter suits Minecraft Java Edition players who want to create and export custom maps by shaping terrain and painting landscape details. It is less suited to users whose main need is editing existing maps or customizing biomes while Minecraft generates the terrain.

Getting started

1. Visit the WorldPainter website.
2. Use a Windows, macOS, or Linux system.
3. Install Java 17 or later.
4. Choose an installer for your platform and check its SHA256 checksum.
5. Create a map and export the generated world to your Minecraft saves directory.

Verdict

WorldPainter provides map-making tools across three desktop platforms, with mod block and custom object support. Its focus is map generation, so review its editing and biome limits before choosing it.
