Just Enough Building Blocks
by Mingli29
Just Enough Building Blocks adds vertical slabs and other partial block shapes for Fabric, so builders can place finer cuts than the standard full cubes allow.
What it does
The mod targets builders who find full cubes too bulky for detailed work. It adds shapes such as vertical slabs and other partial blocks that fill gaps in vanilla's block palette, and the new shapes take the same textures and appearance as their vanilla counterparts. Installation covers the server and each player's game. Builds are released for Fabric across 12 release versions, 1.20.1 – 1.21.10, under the MIT License, and the project is open source.
Key features
Vertical slabs
Slabs placed vertically, giving builders thin walls and panels that full blocks cannot produce.
Precise block shapes
Partial block shapes for small details such as trims, ledges and corners, aimed at finishing touches on a build.
Native look
New shapes take the textures and look of vanilla blocks, so they blend into existing structures.
