Fields

A vanilla-friendly worldgen mod that adds large, handcrafted farm fields to plains biomes. Complete with access roads, fences, and irrigation ditches, these structures blend into the landscape and make the overworld feel truly inhabited.

Install on the server (or in singleplayer) — client installation is optional. Vanilla clients can join and explore the generated fields seamlessly.

Dependencies: Fabric and Quilt need Fabric API. Forge and NeoForge need no additional dependencies.

Free to use in any modpack — public or private, no permission needed.

What it does

• Spawns 8 terrain-aware field variants, adapting to sloped ground, riverbanks, and flat terrain.
• Cultivates a single crop type per field for a realistic, unified agricultural look.
• Surrounds crops with immersive details like wheel ruts, dirt piles, and meadow transitions.
• Adds zero custom blocks or items — pure vanilla worldgen that works right out of the box.

Field variants included:

• Plains row fields
• Terrace fields
• Lowland fields with irrigation channels
• Riverbank fields
• Village-edge farm plots
• Abandoned fields (overgrown, with dead bushes)
• Pumpkin fields
• Melon fields

Crop families used by cultivated areas:

• Potatoes
• Carrots
• Wheat
• Beetroots
• Pumpkins
• Melons

Details

• Existing worlds — fields only generate in newly generated chunks, so previously visited terrain is untouched.
• Removing the mod — already-generated fields remain as ordinary blocks; only future generation stops.
• Other mods — works alongside vanilla villages and other structure mods. Fields use their own structure set and biome tag, so they don't conflict.
• Experimental Settings screen — on some versions the game treats custom worldgen as experimental and asks once when you open a world. Hit Proceed and the world remembers it.
• Locate command — /locate structure fields:field

Tuning for modpack authors

Worldgen ships as a regular datapack inside the jar, so anything you can tweak in a datapack you can override with your own datapack at higher priority:

• Spawn frequency — data/fields/worldgen/structure_set/fields.json (spacing, separation, salt).
• Allowed biomes — data/fields/tags/worldgen/biome/field_biomes.json. Default is plains and sunflower plains; add e.g. minecraft:meadow for wider coverage.
• Variant weights — data/fields/worldgen/template_pool/field/start.json. Higher weight means that variant is picked more often.
• Placement behavior — data/fields/worldgen/structure/field.json (terrain_adaptation, project_start_to_heightmap, spawn_overrides).
