With a small function we can easily changing / replacing the biome of a single chunk : Code:java /*** Set the biome for a chunk.** @param chunk The chunk.* @param biome The biome to set.*/ public void setChunkBiome(Chunk chunk, Biome biome) {for(int x = 0 ; x < 16; x++) {for(int z = 0 ; z < 16; z++) {final Block block = chunk.getBlock(x, 0, z);block.setBiome(biome);}}} With some modifications, we can replace biomes : Code:java /*** Replace the biome for a chunk.** @param chunk The chunk.* @param oldBiome The old biome.* @param newBiome The new biome.*/ public void replaceChunkBiome(Chunk chunk, Biome oldBiome, Biome newBiome) {for(int x = 0 ; x < 16; x++) {for(int z = 0 ; z < 16; z++) {if(chunk.getBlock(x, 0, z).getBiome() == oldBiome) {final Block block = chunk.getBlock(x, 0, z);block.setBiome(newBiome);}}}} Thanks to the french developper Likaos for the first function !
I know that stuff like this works, but is it still that biome after you regenerated the area with worldedit? Last time I checked not.
