Effortless Building Mod 1.19.2, 1,18.2 allows you to mirror and duplicate your builds super easily. Inspired by the modifiers in Blender, this mod makes building easier by providing tools like mirrors, arrays and quickreplace.

  • Mirror blocks in realtime, as you place them. Works with even and uneven builds (add .5 to the position). Rotates blocks like stairs, logs, slabs, pistons etc properly. Multiplayer friendly (separate settings per player).
  • Set position, radius and what axes to mirror by pressing the + key on the numpad.
  • Mirror settings:
    • Position: where the mirror is situated in the world.
    • Direction: what axes to mirror, can mirror on all axes simultaneously.
    • Size: how many blocks away from the position the mirror will still work.
    • Set to current pos: set the mirror’s position to the current player position.
    • Show lines and area: helps visualize where the mirror is.

Effortless Building Mod Features 1


  • The array modifier copies your build in a certain direction a certain number of times. Very useful for nether tunnels but also useful for quickly building walls etc.
  • It is possible to add offset to multiple directions so diagonal builds are possible (e.g. a nether tunnel that goes upwards or sideways). And of course breaking blocks is also supported for if you make a mistake.
  • Set offset and count by pressing the + key on the numpad.
  • Array settings:
    • Offset: in what direction to replicate your block. Example: with offset (2,1,0) and count 3, placing a block at (0,0,0) will also place blocks at (2,1,0), (4,2,0) and (6,3,0).
    • Count: how many times to replicate your block.

Effortless Building Mod Features 2


  • Press the (minus) key on the numpad to toggle QuickReplace. When on, new blocks you place won’t be put on the block you are looking at, but replace it. Handy for swapping out floors or replacing materials in general.


  • Mirror, array and quickreplace all work with each other.
