RoadArchitect is a Fabric / Quilt / NeoForge mod for Minecraft 1.21–1.21.8 that automatically scans the world for villages and other structures and connects them with roads to form a persistent travel network.
Roads adapt their style to the biome, and the network is saved between game sessions.
Current version:
v1.5.0

- In singleplayer, clicking a node in the debug view teleports you to it.
v1.5.0 — Smarter pathfinding, Terrain Analyzer (beta)
- 🧭 Terrain Analyzer (beta): clearer recognition of mountainous terrain, with new config options and full translations
- 🧠 Pathfinding controls: configurable land preference and water behavior (acceptable water level, coastal buffer, max coastal speed)
- 🛣️ Partial paths: when a full route can’t be completed, high-progress searches can return the best partial path instead
- 🌊 Safer defaults: oceans are no longer hard-blocked; default “prohibited biomes” now include
#minecraft:is_oceanand#minecraft:is_deep_ocean - 🔒 Stability: thread-safe biome selector cache (eliminates race conditions in concurrent scans)
- 🔧 Fixes: correct player direction on the debug map and reliable point teleportation packet handling; RA config tweaks
- 🧩 Compatibility: improved boot behavior when Distant Horizons is installed
- 🌐 Localization & data: updated category labels, new keys for fresh options, translations split and refreshed (EN/RU/ES/FR/DE/ZH/UK)
Compatibility: No world resets needed. Defaults for water/ocean behavior changed — review new pathfinding options if you rely on custom configs.
v1.4.0 — Add-ons support
- 🧩 Add-ons support: official API so other mods can extend Road Architect (events, read-only core views, and per-world storage);
- 📴 No changes out of the box: there are no built-in add-ons; gameplay stays the same unless you install one.;
Compatibility: No visible gameplay changes by default; add-ons are optional.;
v1.3.0 — Smarter scans & deterministic decorations
- 🧠 Smarter scanning: major performance boost for large-area scans and many structure types—smoother gameplay, cleaner road graphs, and more reliable structure detection.
- 🌲 Deterministic decorations: consistent, per-path placement of decorations (lamps, buoys, side pieces) across chunk loads—less pop-in and cleaner chunk borders. Also fixes common issues like floating fence posts or off-grid buoys.
- 💡 New Lamp decorations: fresh styles and better fence integration where appropriate.
- 🧭 Debug map: shows your position and direction (red dot + arrow).
- ⚙️ New settings (all loaders):
- Lamp interval
- Side decoration interval
- Buoy interval
- Mask erosion near land/water transitions
- Toggle for deterministic decorations
- 🛤️ Smoother road profiles: post-processing reduces spikes and clamps extreme slopes for cleaner elevation transitions.
- 🌐 Localization & UI: updated strings (EN/RU/ES/FR/DE/ZH) and a small progress-stage label fix (“initialisation”).
Compatibility: No breaking changes; existing worlds remain compatible.
v1.2.0 — Vanilla loading, convenient settings, visual debug
- 🪄 Progress screen: dropped
owo-liband switched to vanilla rendering (Fabric/Quilt and NeoForge), showing the current pipeline stage. - 🧭 Road-graph debug screen: pan/zoom, tooltips, and a color legend; in singleplayer, clicking a node teleports to it. Opens with H.
- 🧰 Settings: Cloth Config on all loaders; Mod Menu support (Fabric/Quilt); Catalogue support (NeoForge).
- 🌐 Localizations: English, Russian, Spanish, French, German, Chinese.
Compatibility: No breaking changes; existing worlds remain compatible.
v1.1.0 — Smoother paths, smarter junctions, cleaner buoys
- ⚙️ Pathfinding (A* / ARA*): adjusted heuristic, removed early termination, expanded profiling.
- 🏗️ Post-processing: trimming roads near nodes, improved junction merging and stabilization.
- 🌊 Buoys: placed only on “clean” water, spaced by real distance, interval increased 12 → 18.
- 🔧 Fixed client ↔ server sync when registering command arguments.
- 🐛 Fixed swamp style: uses
MOSSY_COBBLESTONE_WALLinstead ofMOSSY_COBBLESTONE. - 📦 Reduced mod size.
Compatibility: No breaking changes; worlds from 1.0.1 remain fully compatible.
Is this mod server side? or is it both server-client sided?
The mod is both server and client sided.To join a server, the mod must be installed on both the server and the client.
Does it work with the Terralith world-generation datapack?
Yes — RoadArchitect is fully compatible with Terralith. Roads scan and connect structures in Terralith biomes out of the box.Only villages are being connected?
Not only! RoadArchitect can connect any structure discoverable via /locate structure. Add the structure IDs or a #tag in the config, then reload/restart the world to rescan.
