Tired of the jagged, uneven bedrock layer ruining your builds at the bottom of the world? Flat Bedrock Mod by Sunekaer replaces the randomized bedrock generation in both the Overworld and Nether with clean, flat layers — making mining, building, and navigating the lowest depths far more practical. With over 324,000 downloads and support for Forge, Fabric, and NeoForge, this lightweight utility mod has become a staple for players who want a tidier world foundation. You can even add custom dimensions via a simple JSON config file.
Key Features
- Flat Overworld Bedrock — Generates the Overworld bedrock floor as a single flat layer instead of the vanilla randomized pattern, giving you a clean surface to build on at Y=0.
- Flat Nether Bedrock — Flattens both the floor and ceiling bedrock layers in the Nether, making Nether roof access and sub-floor builds much easier.
- Custom Dimension Support — Add any modded or custom dimension to the flat bedrock list by creating a simple JSON configuration file. Most dimensions are compatible out of the box.
- Multi-Loader Compatibility — Available for Forge, Fabric, and NeoForge, covering virtually every modern modding setup.
- Wide Version Range — Supports Minecraft versions from 1.7.10 all the way up to 26.1, so both legacy and cutting-edge players are covered.

FAQ
Does Flat Bedrock Mod work on chunks I've already explored?
No — the mod only affects newly generated chunks. Bedrock in areas you've already visited will remain in its original uneven shape. You'll need to explore new territory or use a world reset to see flat bedrock everywhere.
Can I use Flat Bedrock Mod with other world generation mods?
Most world-gen mods work fine alongside Flat Bedrock. However, if another mod also modifies bedrock layer generation, there may be conflicts. The mod supports custom dimension configuration via JSON, which helps with compatibility.
Does this mod work in modded dimensions?
Yes — while the Overworld and Nether are flattened by default, you can add any modded dimension by creating a custom JSON configuration file. According to the developer, most dimensions should work with this setup.
