BiomePainter is a runtime biome editing tool that lets you change biomes in existing worlds without regenerating terrain.
It allows you to replace biomes in an area, store those changes as persistent regions, and reapply them later if needed. Regions are saved automatically and survive restarts, making it easier to manage large-scale biome projects without having to repeat the same work.
The mod includes commands for painting, converting, inspecting, deleting, and restoring biome regions, along with undo support because people make mistakes and sometimes turn half the world into a desert by accident.
Changes are synchronized between the server and connected players, and a lightweight API is available for developers who want to build on top of BiomePainter.
