About this Mod
Hello, everyone. First of all, I strongly recommend that you download projects through the official curseforge and modrinth launchers—this will increase the reward for the creators. Thank you all very much for your support!!!
This mod allows you to instantly build lines, columns, walls and floors by easily setting the size with your mouse cursor using just one key on your keyboard (default is the right shift key).
"If you are tired of building identical parts for your incredible structures, constantly clicking the mouse button to place each block, this mod will save you from this tedious routine!"
Dependence:
Usage
Go to settings. Set the key to activate selection mode. There are 4 modes in total:
First mode - "1D"

Second mode - 2D



Third mode - 3D


Fourth mode - 3D Openbox (available only starting with version Smart Build Lib 2.2.0)


After that, set the first block, move to the other side and set the second block, after which the selected area will be filled with the same blocks as the first one in exactly the same position.
In addition, when switching to selection mode, the range of interaction with blocks increases to 20. This can be configured in the configuration file.
Please note that the creation of structures depends on the position of the first and last blocks you click. If you click on the first block and move in a direction where there are no blocks, pay attention to the position of the mouse pointer. If you move the cursor slightly below or slightly to the side, instead of creating a single line, you'll create a wall or floor.

Smartbuild server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.6). You can switch loaders with one click in the panel.
Is Smartbuild compatible with fabric and forge and neoforge?
Smartbuild officially supports fabric, forge, neoforge for Minecraft 1.21.6, 1.21.5, 1.21.4. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Smartbuild – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Smartbuild consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
