FlatBedrock Xplosion's Edition: Perfectly Flat Bedrock
Minecraft's natural bedrock layer is a chaotic mess of jagged protrusions and uneven surfaces. Whether you are digging a tunnel through the Nether or excavating a perimeter down to the void, this irregularity is a constant annoyance. The solution is a lightweight utility that enforces a strict horizontal plane on this indestructible layer. This add-on is an essential pick for any modpack that values clean aesthetics and efficient automation.
Core Functionality and Default Behavior
This mod is designed to eliminate the bumpy terrain of the bedrock layer without altering its block composition. By default, it levels the bottom layer in the Overworld and both the floor and ceiling layers in the Nether. This results in a perfectly smooth surface that is ideal for constructing massive hub tunnels, building precise farms, or simply maintaining a tidy underground base.
The modification does not change the type of blocks; it only changes the shape of the generation. It replaces chaotic outcrops with a strict horizontal line, making the game world much more orderly and easier to manage. For most standard dimensions, this default setup is all you need.
Configuration Files for Custom Dimensions
All settings are managed through JSON files located in the /config/flatbedrock/dimensions/ directory. The mod creates two standard files upon first launch: overworld.json and nether.json. These files contain parameters such as dimID (the numerical identifier for the dimension), genTop and genBottom (toggles for generating flat layers on the ceiling or floor), and fillBlock (the block used to replace bedrock during retro-generation).
For the Overworld, the default fillBlock is stone, but you can change it to any other block, such as netherrack or end stone, depending on your needs. This flexibility makes the mod highly adaptable for custom pack design.
Adding Support for Modded Dimensions
If your modpack includes dimensions from other mods like Twilight Forest, Aether, or Betweenlands, you can easily extend the flat bedrock functionality to them. You simply create a new JSON file in the same config folder, name it after the mod (e.g., twilightforest.json), and input the correct dimID (for Twilight Forest, this is typically 7). The parameters work identically to the standard files, allowing you to enable a flat floor, ceiling, or both.
It is recommended to launch the game once after installing the mod to see if the dimension mod already includes a built-in config file. Some modders integrate support for this utility directly into their code, which will generate the file automatically.
Retro-Generation for Existing Worlds
One of the most powerful features is the ability to flatten bedrock in areas that have already been generated. To use this, you must install the UniversalCore library. Once installed, set retroGenBottom or retroGenTop to true in the relevant JSON file. Upon loading the world, the mod will regenerate the specified layers, replacing the uneven bedrock with the block defined in fillBlock.
It is crucial to back up your world save before performing this operation. While the mod is stable, any modification to world data carries a risk of data loss.
Developer Integration via IMC Messages
Mod developers can integrate this utility without requiring players to create JSON files manually. By sending an IMC (InterModComms) message with parameters like the dimension ID, generation flags, and fill block, modpacks can automatically register flat bedrock for any custom dimension. This is particularly useful for large packs with dozens of unique worlds, ensuring a seamless player experience without manual configuration.
Version Compatibility and Loaders
This utility was originally built for Minecraft 1.7.10, but the 1.9.4 version functions without issues on Minecraft 1.10. Later versions of the game are generally supported, though you should always verify compatibility with your specific launcher and mod loader. The mod is minimalist and does not conflict with most world generators, though Mystcraft dimensions require special attention. In the 1.7.10 version, the planned support for Mystcraft via special pages was not implemented, so users of that mod will need to seek alternative solutions.
Final Assessment
If you are looking to download FlatBedrock Xplosion's Edition: Perfectly Flat Bedrock, you are getting a small yet incredibly useful tool for anyone who values order and precision in their builds. It does not add heavy mechanics, does not strain system resources, and is easy to set up even without deep technical knowledge. Whether you are constructing a large hub tunnel in the Nether or a neat mine shaft to the bottom of the world, working with a flat bedrock layer is significantly more pleasant.
To get the most out of your modpack, knowing how to install and configure this utility is straightforward. The thoughtful configuration system and IMC support ensure that FlatBedrock Xplosion's Edition: Perfectly Flat Bedrock for Minecraft integrates smoothly into any modded setup, making the game world cleaner and more convenient to navigate.
