About Architecture Extensions
From ModrinthA mod that allows you to make more detailed builds with all kinds of new building blocks and shapes.
Temporary PSA
Soul Ice and Aurora's Deco blocks were "removed" when the mod was rewritten. Back up your worlds when upgrading to Arch-Ex 2.About
The mod idea for Architecture Extensions is technically based off the old ArchitectureCraft mod from MC 1.8-1.10 but the key differences are the block models retain the Minecraft pixelation and there are new blocktypes added.
