BiomeTweaker Mod for Minecraft 1.12.2/1.11.2


The BiomeTweaker mod does exactly what the name implies, it allows you to alter biomes in Minecraft. A biome is essentially defined as a region with its own distinct look and conditions. Biomes are an integral part of the Minecraft experience because they allow players to experience different types of environments. There are various different kinds of biomes such as Jungles, Deserts, Tundras and various other, and each of these of course has its own conditions. If you’ve been playing this game for a while, then you’ve probably run into instances in which you wanted to change a certain characteristic of a biome due to a certain reason but couldn’t because this, unfortunately, isn’t supported by vanilla Minecraft.



By using the BiomeTweaker mod, you’ll be able to customize essentially every single aspect of a biome according to your preferences so that your gameplay experience can be more immersive and more in line with your specific likings. The key goal of this pack is to give pack creators a lot more breathing room when designing their mod packs, but it can be used in a variety of other ways as well. It must be said that learning the BiomeTweaker can be slightly difficult because you need to write actual scripts in order to implement the changes that you want to and writing scripts is something that not many Minecraft players are familiar with.


The BiomeTweaker mod implements its biome changes during the world generation process which is why it’s important for the mod to be installed server-side only otherwise its functionality might be hindered. As of right now, the mod has complete support for vanilla biomes, but it’s worth mentioning that there’s a minor chance of it struggling to work with biomes that have been implemented through other mods.
