Building Update
by itzfedd
Building Update adds terracotta, concrete, stairs, slabs, walls and glass walls, and a stonecutter route for crafting them.
What it does
Players pick blocks and craft stairs, slabs and walls from them with a stonecutter, which opens building options for decorated structures. The mod runs on the client alone, so servers need nothing to host it. Builds exist for 1.21.4 and 1.21.8, with 1.0.0 for 1.21.8 as the latest NeoForge file, under All rights reserved.
Key features
Stonecutter crafting
A stonecutter turns chosen blocks into stairs, slabs and walls, so players can shape building materials directly.
Terracotta and concrete blocks
Terracotta and concrete variants join the set of placeable blocks, adding colors for facades and interiors.
Glass walls
Glass walls and matching stairs and slabs let players build windows and open rooms with a consistent style.
