draw the world

Custom World Painter & Generator This mod adds a fully custom world creation option to Minecraft’s new world menu. You can manually draw and paint biome regions on a 2D map canvas, freely configure spawn rules for mobs and structures with flexible whitelist and blacklist systems, and enable forced generation for any buildings you want to appear in specific areas. The mod automatically detects biomes, entities and structures from most installed mods, maintaining full compatibility with common modpacks. It includes 10 ready-to-use preset world templates for quick start, while also allowing full DIY editing: you can adjust terrain distribution, mob spawn restrictions, structure generation limits, and save your customized world schemes for reuse in future worlds. All custom settings are applied only during world generation, without affecting existing saves. Whether you want to build medieval kingdoms, vampire realms, adventure continents or unique custom landscapes, this tool gives you complete control over your world generation logic without editing JSON files or external datapacks.
