World transforms.

The transforms a generated world can stack: replace, randomize, layers, skygrid, strip, and cut.

Run on each chunk, in order.

A generated world's transforms run after the base shape and its decorations, each over the whole chunk, in the order they are stacked.

  • Replace blocks

    replace

    Blocks of some kinds become others.

    Fields

    These blocks (from)
    kinds of block, tags included, required. Ids and tags.
    Become one of (to)
    kinds of block, required. Ids; one is picked at random.
    Chance (chance)
    a whole number, 1 to 100, optional. The percentage swapped; all when left out.
    Decided (per)
    block or chunk, optional. Each block for itself, or once a chunk.

  • Random blocks

    randomize

    Every block that isn't air becomes one of some kinds, picked per block, chunk, layer or column.

    Fields

    Blocks (blocks)
    kinds of block, or "any", required. Ids, or any block that can be placed.
    Chance (chance)
    a whole number, 1 to 100, optional. The percentage changed; all when left out.
    Picked (per)
    block, chunk, layer or column, optional. Once per block, chunk, layer or column.
    Liquids too (liquids)
    yes or no, optional. Change water and lava as well.

  • Layer cake

    layers

    Every block of a height becomes one kind, the same in every chunk.

    Fields

    Blocks (blocks)
    kinds of block, or "any", required. Ids, or any block that can be placed.
    From height (from)
    a whole number, -64 to 319, optional. The lowest height changed.
    To height (to)
    a whole number, -64 to 319, optional. The highest height changed.

  • Skygrid

    skygrid

    Everything goes; one random block stands at every point of a grid.

    Fields

    Spacing (spacing)
    a whole number, 2 to 16, required. Blocks between grid points, 2 to 16.
    Blocks (blocks)
    kinds of block, or "any", required. Ids, or any block that can be placed.
    From height (from)
    a whole number, -64 to 319, optional. The lowest height of the grid.
    To height (to)
    a whole number, -64 to 319, optional. The highest height of the grid.

  • One strip

    strip

    Only a strip of the world stays; the rest is air.

    Fields

    Along (axis)
    x or z, required. Which way the strip runs.
    Width (width)
    a whole number, 1 to 64, required. How many blocks wide, 1 to 64.
    Starting at (at)
    a whole number, -30000000 to 30000000, optional. The coordinate the strip starts from; 0 when left out.

  • Cut

    cut

    Everything below or above a height goes.

    Fields

    Below (below)
    a whole number, -64 to 320, optional. Remove everything under this height.
    Above (above)
    a whole number, -64 to 320, optional. Remove everything over this height.
