Each file lists exactly the Minecraft versions it was built and tested for, and loaders will refuse it
on anything else — so pick the file that matches your version.
Requires: Fabric API on Fabric. Nothing else — Architectury API is no longer needed as of 2.0.0.
Multiplayer
The mod is client-side: you can design, preview and save schematics on any server.
- Printing into the world needs operator permission, the same bar as
/setblock. On a server
without the mod it places blocks with ordinary commands, batched and rate-limited. - Servers and LAN hosts can install it too. Since 3.0.0, players without the mod can still
join. With it on the server, printing is faster, skips the chat spam and also works for players
in creative mode. Placements still respect the world border, spawn protection, claims and reach.
Server admins: do not run a 0.x build on a server. Versions before 2.0.0 accepted build packets
from any player without checking permissions. Update to 2.0.0 or newer, or simply remove the mod from the
server — players lose nothing. If a server ever ran an older build, also check/gamerule logAdminCommands.
Making themes
Press G, edit a theme, then 1 for the exporter toolkit (creative mode). The tools are
vanilla items: a blaze rod exports, a lodestone marks each design, and glazed terracotta marks its
layers. The mod labels them and outlines each design while you work.
Coming from 2.x? The old marker blocks disappear from your worlds. Exported designs are fine.
Your themes and palettes
Since 2.0.0 your own themes and palettes live in <game folder>/mightyarchitect/. Existing ones are
copied there on first launch; the originals are left untouched. Resource packs can now ship complete
themes under assets/mightyarchitect/themes/<name>/.
