The places that have been built on in my world aren't that big. It's a ~100x~100 square, a ~150x~50 rectangle in the Nether, and another ~100x~100 square accessed by portals.

The world is currently unplayable due to the server console spending so much time printing errors that the players time out. That, and for some reason it decided to spawn hundreds of sheep.

So I was wondering, is it was possible, and if so how, to move sections of this world into another, new, world?

  • I may be wrong, but MAYBE the biome information is not saved together with the chunks. I read about that here: getsatisfaction.com/mojang/topics/… (but that info might be outdated, I don't know). — Well, I asked about this: gaming.stackexchange.com/questions/27634/… Aug 10, 2011 at 21:29
  • @Denilson I am fairly certain that biomes are saved separate from the chunks because I have had biomes changed. Aug 10, 2011 at 21:36
  • Pasting into a different map will almost certainly result in a biome mismatch. This may mean your desert in your old map is now tundra, and while the terrain will stay the same, it may snow...

  • @John I have the same problem with my minecraft world! It's not running as a server, only at home on my local PC and my favorite and giant world is not accessible anymore. One time I managed to move my character with an lvl editor and I saw hundreds of cows. It would be a pity if I had to give up this world. Did you manage to save your world with fredley's proposal?

  • @Exa I didn't try. Knowing that the biomes would never be the same, I decided to just start a new map. In your case however, if you have the original seed (I can help you get the current seed, but if it has changed you will still have a biome mismatch), then you can create a world with that seed and copy your other world in. That will guarantee a biome match because both worlds were generated from the same seed. I don't have my original seed, so that wouldn't have worked for me. Aug 11, 2011 at 14:25

Yes. Use MCEdit. You can copy the section in your old map, and save it as a schematic, which you can then import and place into a new world (generated with Minecraft by starting a new game), overwriting what was there before. Make sure Minecraft is closed while you are using MCEdit, otherwise you can corrupt your map.

  • Do you have to copy the saved chuncks into another existing world, or can you save the selectioned chuncks of your old world, that you want to keep, and generate a new "world" around it? What I mean: Cutting a part of the old map out, keep this, and delete the rest, so that there will generate new/unused biomes around it? Greets and thank. :)

  • There is a prune operation on mcedit which will remove all chunks except the selected ones.

  • Personally I prefer Worldedit. It can perform most MCEdit operations, but from in-game. Also, it exists for Forge, Bukkit and more mod systems.

    MCEdit is long dead unfortunately. NBTExplorer can do things like this but is also rapidly aging and is incompatible with Minecraft 1.16+ as of this writing. I have, however, found MCASelector just recently and am going to be using it later, it seems to be frequently updated to this day. I'll follow up if I have success with it.

Got a server copy of Minecraft with Forge installed?

If you want to copy a region of your world, you can now just use MCEdit.

  1. Open the world you wish to extract something from.
  2. //wand to get a wooden axe tool wand to select your region.
  3. LMB and RMB (first and second point) the tool wand on the blocks marking the cuboid you wish to extract.
  4. /schematic save [-f] <filename> to save your region to a .schematic file.
  5. Exit out and open the other world you wish to put things into.
  6. /schematic load <filename> to load your exported area (from Step 4) to the clipboard.
  7. Stand in the location you wish to place your structure in and then type //paste.

If you made a mistake (ie. stood in the wrong corner without wanting to deal with the hassle of rotating), you can just //undo and //redo your action. See the official documentation for more info.

If you want to just copy whole chunks at a time, you Querz/mcaselector allows you to do just that.
