Litematica Printer - Hana Version

This mod adds automatic building features to Litematica for Minecraft Fabric versions from 1.18.2 to 26.2.
It allows players to quickly rebuild schematics by automatically placing the correct blocks around the player.

This is an independent fourth-generation fork, separate from the previous third-party modified versions.
The main features include independent bedrock-breaking logic and many additional quality-of-life improvements.

If you find this project useful, please consider giving it a Star ⭐️ to support the project.

[!TIP]

There is currently no official tutorial, but most features include comments or descriptions inside the mod settings.

Unsupported Blocks

The following blocks are not supported yet due to special placement or entity-related behavior.
The printer will automatically skip them, or they may appear as incorrect printing states.

If you find other blocks being placed incorrectly, try lowering the printing speed first.
If the issue still happens, please submit an Issue.

Unsupported blocks include:

  • Skulls, signs, banners, and any blocks with 16-direction placement
  • Cauldrons containing fluids
  • Entity-based blocks, including but not limited to item frames, armor stands, paintings, and similar entities
  • Non-vanilla game content

FAQ

Why does the printer not work after being enabled?

Possible reasons:

  1. The printer works by silently sending rotation/look packets for block placement.
    It does not fully validate whether the clicked face is legal, so it may be blocked by server anti-cheat systems.

  2. The Printer Working Interval may be too low.
    Some servers, such as those using Luminol or other placement rate limits, may not respond quickly enough.
    Try enabling Data Packet Printing, or increase the printer working interval.

  3. In some rare cases, servers with online-mode authentication may have abnormal packet interaction after login.
    Try re-logging into your Minecraft account.
    Using the Auth Me mod is recommended.

If none of the above solves the issue, please submit an Issue.
The developer will try to help you resolve the problem.

Why are some blocks placed incorrectly?

Possible reasons:

  1. The server has anti-cheat plugins, which may prevent the printer from simulating looking and placing correctly.

  2. The printer working interval is too low, and the server cannot respond in time.
    This is a normal issue under high-speed printing. Try increasing the Printer Working Interval.

  3. The recognition algorithm may not support the specific block yet.
    Please submit an Issue and describe which block is placed incorrectly.

Why does Quick Shulker not work?

Possible reasons:

  1. The server does not have a plugin that allows shulker boxes to be opened by right-clicking in the inventory.
    AxShulkers is recommended.

  2. The printer setting does not match the actual supported Quick Shulker mode.
    Please adjust it to the correct mode.

  3. The pre-selected slots are filled with shulker boxes.
    You need to configure pickBlockableSlots in Litematica settings.

Example:

Preset Slots

Quick Shulker support is still experimental and may have issues.
If you encounter problems, please submit an Issue.
