void building

I want a mod that allows placing block/items under the bedrock layer of the overworld void and beneath (with a block supporting it). I want the void to act...

Void Building

  • Overworld depth extended downward (min Y -128) while keeping the usual surface height; you can now place blocks beneath the bedrock layer.
  • Chunks are prepared on first load: everything below Y -64 is converted to void air and a bedrock band is rebuilt at Y -64 to -60 with vanilla-style randomness.
  • Players in the overworld start taking void damage once they reach Y -115.
  • Chunk preparation is tracked so it only runs once per chunk; works on both newly generated and existing chunks when they load after installing the mod.
  • Runs on both client and server; expects to own overworld dimension settings, so other mods that alter the overworld height/noise may conflict.
  • Void damage applies to all players, including creative/spectator, matching vanilla behavior aside from the higher trigger height.

Server Validation

Server validation passed - The mod was tested on a real Minecraft server and loaded successfully.
