Effortless Building FAQ

Craft it like you would any other tool in the mod, then keep it in your hotbar. Once it's selected, the mod's randomizer overlay appears so you can configure which blocks get swapped in.

Hold the Randomizer Tool, open its configuration screen, and add the blocks you want it to pick from into the randomization list. Then place blocks normally with Effortless Building's modes active and each placement pulls a random entry from that list.

Open the Randomizer Tool's config screen and add block entries to its list — each entry is a block the tool can substitute in. Anything not on the list won't be used, so the list is what controls your palette.

Yes — the randomizer supports weighting entries, so a block with a higher weight appears more frequently in the mix. Use this to make one block the dominant texture and others occasional accents.

You probably have too many visually distinct blocks in the list, or the weights are too even. Trim the list to a few similar-toned blocks and give the main one a heavier weight so it dominates.

Check that the Randomizer Tool is the item you're holding and that its list actually contains blocks. If the list is empty or the tool isn't selected, placements fall back to normal behavior.

Yes — the randomizer applies per block as the mode places them, so a wall or cube built with a mode gets randomized block-by-block. That's how you get large natural-looking surfaces in one action.

Yes — just toggle the Randomizer Tool off (or switch away from it) when you want uniform placement, and back on when you want randomization. The list persists, so you can flip between the two freely.

Large placements are heavier because each block is chosen individually, so very big operations can hitch briefly. Break the build into smaller chunks or reduce the list size if you notice stutter.

It works with any block that can be placed normally, including blocks added by other mods, as long as you can add them to the list. Blocks with special placement rules or tile entities may not behave as expected.

It makes building easier by providing tools like mirrors, arrays, build modes and a block randomizer. It lets you place and break multiple blocks at once, mirror blocks in realtime, and undo and redo, and it works in both survival and creative mode.

The mod lists support for Minecraft 1.20.1, 1.21.1, 1.21.5, 1.21.11, 26.1.2 and 26.2.

It is available for Fabric, Forge and NeoForge.

The available build modes are Disabled, Single, Line, Wall, Floor, Cube, Diagonal Line, Diagonal Wall, Slope Floor, Circle, Cylinder and Sphere. You select them from the radial menu that opens when you hold ALT.

Hold ALT to open the radial menu and select a build mode, then with a block in hand right-click to pick the starting position, aim somewhere else and right-click again to build the shape. Build modes can also be used to break blocks and to interact with blocks, for example stripping logs with an axe or tilling with a hoe.

The Randomizer Tool is an item that lets you place random blocks, and you configure it by shift-rightclicking while holding it. It can be used together with build modes and build modifiers, and setting the ratio of an empty slot causes air gaps to appear in your shape.

The modifiers are Mirror, Array and Radial Mirror. Mirror places a mirror at a position of a certain size so each block placed on one side is mirrored to the other, Array copies the block you placed in a certain direction a certain number of times, and Radial Mirror divides an area in slices around a central point where each slice copies your block placements.

Yes, the mod is fully supported in survival mode as well as creative mode.

It registers the Randomizer Tool, which is the item used to place random blocks. The mod focuses on building tools and build modes rather than adding new blocks.

Hold the ALT key to open the radial menu, where you can switch between build modes and access tools and options. The right side of the menu has additional options for each build mode, and the left side has buttons for undo/redo, replace options, modifier settings and the config screens.
