Flatten Bedrock is a lightweight NeoForge mod designed to clean up Minecraft’s uneven bedrock layers.
Instead of the normal scattered bedrock pattern, the mod converts bedrock boundaries into a single, clean, flat layer.
Features:
- Flattens bottom bedrock layers
- Flattens ceiling bedrock layers, including the Nether roof
- Works in the Overworld, Nether, and other dimensions that use standard bedrock boundaries
- Supports newly generated chunks
- Supports existing worlds
- Existing chunks are automatically corrected when they are loaded
- Does not force-load the entire world
- Designed to keep processing lightweight and avoid large lag spikes
- No new blocks, items, recipes, or textures
Existing worlds do not need to be regenerated. Simply install the mod and explore or revisit chunks to have their bedrock layers corrected automatically.
Flatten Bedrock is ideal for players who prefer clean world boundaries for mining, building, technical projects, or general world cleanup.
