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.

Frequently Asked Questions

Architecture Extensions server crashes on startup – what to do?

Most common cause: wrong quilt 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 (1.20.4). You can switch loaders with one click in the panel.

Is Architecture Extensions compatible with quilt?

Architecture Extensions officially supports quilt for Minecraft 1.20.4, 1.20.1, 1.19.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Architecture Extensions – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Architecture Extensions 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.
