BuildPrint

With the walkthrough that opens the first time you join a world. It shows how to load a build, put it in place, read the colours and build it, with small live scenes, and lets you set your keys. It takes a minute.

Skipped it? Type /buildprint onboarding in chat to run it again. After that, Getting started covers the same ground in more detail.

B. Up to 0.1.25 it was M, and a video or an older answer may still say so. A key you set yourself stays as it was.

If B does nothing, another mod probably uses it too. Press Esc, open Options..., Controls... and Key Binds..., and look in the BuildPrint group for Open menu: a key shown in red is taken. Give it another one. See Shortcuts.

Press B to open the menu, pick the file in the Local tab and click Load. It shows as a ghost where you stand. The Local tab lists the schematics folder in your Minecraft folder, so put downloaded files there. Or drop a file onto the game window, or click Place on a build in the Marketplace tab.

Then put it where you want it with the editor (G). See Getting started.

With the editor. Press G, press 4 for Place and left-click the ground where it should go. Then 5 for Move to drag it with the arrows and 6 for Rotate to turn it. Esc when it sits right. Pictures and every tool are on the editor page.

To type exact coordinates instead, open the menu with B and use Position in the Loaded tab. Auto align is only for a build that is already partly standing. See Moving and aligning.

Only if you turn that on. By default you place every block yourself, with the ghost showing where. With easy place (N) you right-click the ghost and the right block goes down the right way.

The printer places the missing blocks around you while you move through the build. Press B, click the gear at the bottom right, and turn on Printer mode (auto-build) in the Building tab. Many servers count the printer as cheating, so check the rules first. See The printer.

You probably have an older version. New versions go up on Modrinth and CurseForge at the same time, but CurseForge checks every file before it shows, and that can take days. The newest version is on Modrinth first.

To see which version you have, look at BuildPrint in Mod Menu on Fabric or the mod list on NeoForge. The changelog says what each version changed.

Fabric on every Minecraft version from 1.21.1 to 1.21.11 and from 26.1 to 26.3, and NeoForge on 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.8, 1.21.10 and 1.21.11 and on 26.1.2 to 26.3. Minecraft 1.21 itself isn't supported: play 1.21.1. There is a file for each version and loader, and every version has everything BuildPrint does. On Fabric you also need Fabric API; Mod Menu is optional. On NeoForge nothing else is needed.

No. Loading, building, the marketplace and joining a session all work without one. You only sign in to like builds or publish your own, and to start a session under your name.

The quickest way is the walkthrough: type /buildprint onboarding, go to the shortcut pages, click a key and press the one you want. Each key has a line on what it does, and one that something else also uses shows in red.

Or in the game's own Controls screen: press Esc, click Options..., Controls... and Key Binds..., and scroll to the BuildPrint group. Click the button next to an action and press a key.

The printer, easy break, the view filter, the status panel, container contents and hiding builds have no key until you set one. A key for Toggle Printer turns the printer on and off without opening the settings, and shows Printer ON or Printer OFF above the hotbar. All keys are on the Shortcuts page.

BuildPrint only runs on your client, so it works on any server you can join. Showing a ghost and the material list change nothing in the world.

Easy place and placing in mid-air make placing much easier than by hand, and the printer places blocks for you. Many servers count that as cheating. Whether you are allowed to use them is up to the server, so check the rules. All three are off by default.

Some servers run a hub, a survival world and more behind one address, which look like one world to your game. So BuildPrint remembers the bedrock under a build when you place it, and only shows the build where that bedrock matches. In another world it is hidden, not removed, and it shows again when you go back to its own world.

If it is hidden in the world it belongs to, go to another dimension and back, or rejoin: the ground under the build may not have loaded yet when it was checked. If the server only has one world, turn off World fingerprinting in the Schematics tab of the settings. See Several worlds behind one address.

Yes. BuildPrint opens .litematic files directly and saves in the same format. On first launch it offers to bring over your Litematica placements, so your builds show up where you left them. Your files are not changed.

Yes, with the editor. Press G to open it (B up to 0.1.25). Pick Select with 1 and click two corners of the build, fit the box with Resize on 2, and save it with Save on 3. The file goes into your schematics/ folder as a .litematic, to load or share. See The editor.

Yes. Load the build, open the Loaded tab and click Paste. It goes in in one go, with chest contents and sign text, and Undo takes it back. Only the layers in view are pasted. See Paste.

In single-player it writes straight into the world. On a server it uses VoxelSprout Policy if the server has it, otherwise Axiom, /fill commands if you are an operator, or WorldEdit. With FAWE the build goes up in one piece, which is much faster. Otherwise, without operator status the server lets commands through at about one a second, so a big build takes a while that way.

That is the layer view. Press B, open the Loaded tab, select the build and set Layers to Off in the View group. The . and , keys turn the layer view on, so a stray press can switch it on.

To see a few layers instead of one, leave it on and use - and + on the Range row. See Layer view.

The ghost shows under Iris shader packs. Players have tested it with Complementary, BSL, Bliss, Photon and I Like Vanilla, also on very large builds and together with Voxy and Better Clouds. The pack does not light or shadow the ghost: it is drawn on top of the finished picture.

Run /buildprint report in game, or click Write a report... in the Help tab of the settings. You see everything that would be sent, with names and paths taken out, and nothing goes until you press Send. When there is an answer, the game tells you. You can also ask on Discord. See Bug reports.
