vGenerate — realistic worlds, fantasy biomes, medieval dungeons

vGenerate is a Paper plugin that rebuilds world generation for all three dimensions — no resource pack, no client mod. Players join with a vanilla client and get ReTerraForged terrain — continents, river networks, hydraulic erosion — with 94 custom biomes, 33 furnished structures and trial dungeons with 18 custom bosses and mobs.

⚠️ vGenerate changes terrain generation, so it is meant for new worlds. Opening an existing world will create sharp borders between old and new chunks.

🏔️ ReTerraForged terrain, now as a plugin

The terrain generator of the ReTerraForged mod (1.21.1) runs inside the plugin:

• continents with shelves, coasts, beaches and island chains;
• terrain regions: plains, steppe, hills, dales, plateaus, badlands, torridonian hills, three kinds of mountains and volcanoes, plus long mountain chains;
• river networks with tributaries, lakes and wetlands — raised water tables fill rivers and lakes high up inland;
• hydraulic erosion and smoothing of the finished heightmap;
• the climate comes from the same map, so vGenerate's biomes land where they belong.

Caves, aquifers, ores, surfaces and structures stay vanilla mechanics; the world spans y -80 → 384, new worlds spawn on land near a continent's centre.

Flexible settings in plugins/vGenerate/terrain.yml: start from one of the mod's presets (default, legacy, vanillaish, beautiful, lite, huge_biomes, rivers) and change any value — continent type and size, coast thresholds, climate and biome size, weight and scale of every terrain type, rivers, lakes, wetlands, erosion. /vgenerate preview [size] [seed] renders a terrain map of the current file in seconds, so you can tune the world before creating it. Prefer the old vGenerate relief? Set mode: classic.

Each biome has its own colours, fog, particles, trees (maples, golden birches, baobabs, olives, willows, giant redwoods…), ground cover and surface blocks — all built from vanilla blocks.

🔥 A darker, grander Nether

The Nether is twice as tall (256 blocks) with vertically stretched caverns and colossal pillars connecting floor and ceiling. 19 custom biomes join the vanilla ones: Ashen Wastes, Glowstone Grotto, Bone Lands, Blood Marsh, Quartz Crags, Ghostfire Valley, Withered Forest, Ash Dunes, Molten Abyss, Demon Crater, Magma Cliffs, Wailing Caverns, Obsidian Badlands, Gilded Depths, Crimson Spires, Ember Forest, Charred Forest, Cinder Fields, Infernal Rift.

🌌 A new End

Beyond the main island, floating sky archipelagos drift above the outer void. The dragon fight is untouched. 17 custom biomes: Chorus Forest, Crystal Spires, Obsidian Wastes, Echoing Void, Shadow Forest, Purpur Mesa, Starfall Fields, Ender Bloom, Dragon Graveyard, Abyssal Scar, Eclipse Plains, Shattered Isles, Void Shoals and the sky biomes Astral Highlands, Celestial Gardens, Phantom Spires, Nebula Reach.

🏰 33 structures

Overworld: Medieval Village (streets, tavern, chapel, smithy, farms, market, guard tower), Castle with moat, keep and treasury, Mage Tower, Bandit Camp, Graveyard with crypt, Ruined Watchtower, Catacombs, Deep Forge, Proving Grounds, Ruined Abbey, Frost Citadel, Pharaoh's Tomb, Witch Coven, Volcano Sanctum, Lighthouse, Druid Circle, Dwarven Gate, Nordic Camp, Windmill Farm.

Nether: Infernal Keep, Soul Shrine, Soul Cathedral, Demon Gate (with a working portal), Warlord Hall, Bone Colossus, Hellforge.

End: Void Sanctum, Crystal Observatory, Void Cathedral, Ender Citadel, Dragon Bones, Abyssal Monolith, Sky Sanctuary.

Every structure is dressed in its own style: window sills and shutters, stone plinths, buttresses on long walls, banners, ivy on old masonry, smoking chimneys, yards with plants and clutter; inside, furniture along the walls, bordered rugs, chandeliers, and cobwebs, chains, skulls and rubble in the dungeons. Doors, stairs, chests and spawners always stay reachable.

⚔️ Trial dungeons, custom mobs and ominous vaults

Dungeons contain trial spawners with 18 custom mobs: Fallen Knight, Bone Archer, Arena Champion, Abbey Wraith, Frost Revenant, Tomb Guardian, Coven Witch, Magma Horror, Soul Reaper, Infernal Knight, Ember Sentinel, Piglin Warlord, Hellhound, Void Warden, Void Stalker, End Knight, Shulker Sentinel and Phantom Wraith. They are vanilla entities with their own names, armour trims, enchanted weapons, attributes and size — so they work with any vanilla client.

Cleared waves drop trial keys. With Trial Omen the spawners turn ominous and drop ominous trial keys for ominous vaults. Every dimension has its own vault loot.

📦 Installation

1. Requires Paper (or a Paper fork such as Purpur) for Minecraft 1.21 – 1.21.11 (Java 21) or 26.1 – 26.3 (Java 25). One jar covers all of them: on start-up vGenerate detects the server version and installs the matching worldgen datapack.
2. Put the jar into plugins/.
3. Start the server with fresh worlds (delete or rename world, world_nether, world_the_end).
4. The datapack is registered automatically. vGenerate also adds worlds.<level>_the_end.biome-provider: vGenerate to bukkit.yml so the End gets its custom biomes.

Find things with /locate structure vgenerate:castle or /locate biome vgenerate:volcanic_peak.

🧩 Version notes

❓ FAQ

• Do players need anything? No. Everything is server-side and uses vanilla blocks and entities.
• Spigot / Bukkit? No — the plugin uses Paper's datapack bootstrap API.
• Existing worlds? Only new chunks change, and the world height changes, so start a new world.
