Flat bedrock is responsible for changing the way the Bedrock layer is generated in Minecraft. Until now, the Bedrock was generated irregularly, creating grooves and ledges, between which a diamond could be trapped and constantly made us jump to traverse this region of the world. But it’s over with this mod.
The mod takes care of turning the rough layer of Bedrock into a smooth and even layer that will be pleasant to walk on and look for diamonds (although not the best height to find diamonds). The same will happen with the Bedrock layer of the Nether dimension.
