Smart Build

One swing, a whole wall.

Smart Build places entire layouts in one go, using ordinary pieces at ordinary cost: grids on all three axes, gaps, stagger, arcs, blueprints of things you have already built, terrain following, and an undo that refunds every last nail.

The idea

Vanilla building is one piece, one click, forever. That is fine for a hut and punishing for a longhouse. Smart Build takes the repetitive half off your hands:

  • Lay a 10 x 10 longhouse floor in one go instead of a hundred aims and a hundred clicks.
  • Run a palisade the length of your border with the spacing set once, not fifty times.
  • Bend a wall into an arc, or a full circle, without lining up a single piece by eye.
  • Save a section you already built and stamp it down the whole coastline.
  • Build across a hillside and let every piece settle onto the ground beneath it.
  • Get it wrong, press Ctrl + Z, and walk away with every resource back in your pockets.

It adds no new pieces and makes nothing free. It just swings your hammer faster.

What it will and won't do

Smart Build will not build anything you could not have built yourself. Every piece costs full price, wards and no-build zones and biome rules all still apply, and if one spot in a grid is blocked the whole placement is refused rather than quietly skipping past it. There is no creative mode hiding in here.

It also stays in its own lane. Everything rides on a separate tool you craft, the Smart Hammer, so your plain hammer keeps behaving exactly as it always has. It is client-side, so nobody else on the server needs it, and everything it puts down is an ordinary piece that stays standing if you ever uninstall.

You will probably like it if you are putting up longhouses, curtain walls, docks, terraced farms, or anything else that has ever had you clicking the same piece fifty times in a row.

You probably want something else if you are after free materials, a creative mode, or anything that reaches the other players on your server.

The time it saves

| What you are building | One piece at a time | With Smart Build |

|---|---|---|

| A 10 x 10 longhouse floor (100 pieces) | 100 aims and 100 clicks | a few seconds |

| A row of 20 stone foundations | 20 | a few seconds |

| A 12 x 2 x 2 curved wall (48 pieces) | 48 pieces, each turned by hand | a few seconds, the curve set once |

| A 30 x 10 palisade (300 pieces) | 300 | a few seconds |

| A 1,000-piece build | 1,000 | a few seconds |

Dialling in a size really is just holding X and scrolling. It stays safe at that scale, too: materials are counted before anything spawns, a blocked spot refuses the whole grid, and Ctrl + Z hands it all back.

Core features

Grid on three axes

This is the heart of it. Instead of placing one piece, you place a grid of them: a longhouse floor, a curtain wall, a tower of stacked layers.

  • Hold X and scroll the mouse wheel (or press the Up / Down arrow keys) for width, Z for depth, X + Z together for height.
  • Hold Shift to move in steps of 10.
  • Press Down past 1 and the axis flips, growing the other way from the piece you are aiming at.
  • Size, gap, piece count, and blocked count all show on screen while you set it up.

Directional arrows

Three short arrows float just above the ghost whenever a grid or blueprint is dialled in, or while you hold X or Z to start one: red for X, green for Y, blue for Z. Each is labelled with its letter at the tip. They point the way each axis grows, so a rotated, staggered, or flipped layout is never a guess. Glance at the arrows, then click.

Gap

Every axis gets its own gap, so you can spread a row out one way and keep it tight the other. Negative values overlap pieces on purpose.

Stagger

Stagger works in every direction, whichever way the grid runs: each piece shifts a little further than the one before, along either of the other two axes. Hold B with X to shift along X (red), with Z along Z (blue), or with both to step up (green). So a row of walls can step up into a stair of wal

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
