Is there a world generator that can create a Minecraft world that's solid rock? Literally, with one layer of bedrock at the bottom and the other 127 layers stone?

I don't care if it generates ores or not since it will be hosted on my server with other normal worlds connecting to it, but it would be a HUGE pain to make a world like that with mcedit or other programs manually.

It would be a huge plus if there's a bukkit plugin that can do that too. =)

Quite the contrary, it seems really easy to do with MCEdit (I've just tried it).

  • Start MCEdit, create a new world. Put in a few numbers - how large a world do you want to have?
  • Once the world is generated, press ctrl + a. That selects the whole world.
  • Select the Fill tool. Pick stone and pres fill.
  • Similarly, fill the bottommost layer with bedrock. (set the selection height to 1.
  • Take care to place the spawn point wherever you like it.

Save, and you're ready to go.

  • I believe ctrl-a only selects all chunks in MCEdit's current working area, but I could be wrong. Does doing this allow walking infinitely far in-game and still getting only flat stone? Commented Aug 20, 2013 at 16:18

World generation now comes with a powerful preset tool. The code for generating one layer of bedrock followed by 127 layers of stone is:

  • Compared to the MCEdit option, his has the added benefit of still working no matter how far off the "edges" of the map you go.

You can download a flat stone world. Just extract to the same location as your other worlds.

  • I needed a solid stone (bedrock to max height) world. =)

  • @KortPleco I think you mean bedrock to a few less than max height. Otherwise, there would be no room for players. :) Commented Dec 11, 2011 at 22:06

    @KortPleco You said bedrock on the bottom layer and the rest stone.

    @John I think he meant the stone should be "from bedrock to max height".

    @John: Players can exist above the map. I think the spawn-point can be placed at max height and the players would spawn half in stone, one jump and they're out.

I'm a bit late to the party, however, I'm quite surprised nobody has mentioned the CleanroomGenerator plugin (http://dev.bukkit.org/bukkit-plugins/cleanroomgenerator/files/6-v1-0-0/). Along with a world management plugin (I use Multiverse), you can create worlds with any combination of layers.
