Painted Biomes

Biome placement is driven by an image: each pixel of the template maps to a biome, and the template can be positioned in the world with three coordinate and alignment options. The mod works by wrapping the biome provider, so the biomes themselves are replaced while the terrain generation logic stays in place. Replacing a biome does not always change terrain, as with the vanilla Nether, and the End looks exactly the same after a biome is replaced.

The mod runs only where the server allows it: a configuration list named enabledInDimensions selects the dimensions it applies to, given by their numbers, and the Painted Biomes dimension can be used as well. Single Template mode places one image in the world and can repeat it, either by tiling the whole image or by extending the biome of its edge pixels outward. Areas beyond the corner of the template are handled by repeating only on the two adjacent sides. Output is deterministic, so the same settings and seed produce the same world, and the repeat behavior of the template depends on its position relative to the world origin.

The mod is published for Forge only, across 13 release versions 1.7.10 – 1.12.2, and is licensed under the GNU Lesser General Public License v3.0 only, which makes it open source. The latest Forge file, 0.5.4 for 1.12.2, was released on 2023-10-16, and the first release came out on 2023-04-17.
