TerraFirmaScout

A seed finder for your next TerraFirmaCraft playthrough, for Minecraft 1.21.1 (NeoForge) and Minecraft 1.20.1 (Forge). The 1.20.1 build is made to work with addons and packs that change world generation, including TerraFirmaGreg.

Maybe you want a river and starter copper close to home. Maybe you are after a specific rock type, a warmer climate, or a forest you can build beside. Or maybe you want a difficult start and a reason to explore.

TerraFirmaScout lets you choose what you are looking for, then searches seeds before you commit to a world.

Choose your start

Pick Dream Start, Easy Start, Fair Start, Rugged Start or Wilderness Start for a quick starting point. For something more specific, open Pick your world and make your own wishlist.

Your wishlist can include:

• Resources and the distance you are willing to travel for them: copper, tin, flux, graphite, kaolin, clay and trees. The 1.20.1 build also offers iron and coal.

• Water: a river, a lake, or the coast or ocean, each with its own distance.

• Farming: enough crops that fit the climate at spawn. On 1.21.1 you can also ask for farmland that rain alone keeps moist.

• Temperature and rainfall, spawn and nearby biomes, surface rocks, forest types, tree cover and spawn height.

• Suitable ground for a camp or a larger build.

If something does not matter to you, leave it open. Scout remembers your wishlist for next time. Results show the forest type and tree density at spawn.

How it works

Open Create World and select the TerraFirmaCraft preset.

Open TerraFirmaScout, choose your settings and click Find a seed.

When a confirmed match turns up, choose Use this seed or keep looking.

Scout uses the world's own generation to check promising candidates in a real temporary world. Every requirement you selected has to pass before you can use a result through Scout, even if the seed has a high match score.

You can pause or stop a search. Matching seeds are saved automatically, and reports can be exported. Resource locations stay hidden until you turn on Reveal.

Versions and requirements

World Preview TFC is not needed.

Addons and TerraFirmaGreg (1.20.1)

Scout reads what your world can actually generate. If a pack removes a resource, that requirement is skipped and the search screen tells you. Features meant for a particular pack only run when that pack's mod is installed.

Tested by launching the real game with Scout's automated checks on TerraFirmaCraft 3.2.25 with Patchouli alone, and on the complete TerraFirmaGreg Modern 0.13.10 pack — all 262 mods — including TerraFirmaGreg-Core, GregTech CEu Modern, KubeJS, Lithostitched, TFC Ruins, FirmaLife and Create.

Addons were tested only as part of that pack.

In TerraFirmaGreg

Scout follows the pack's changed world generation and recognises its ore veins. Searches are slower there, and Pause can take a few seconds.

TerraFirmaGreg removes TFC's loose copper, so that check is skipped.

The Dream, Easy and Fair presets also require iron and coal.

Current status

This is an experimental release.

Very specific requests can take a long time or return no match within the search limit. Finding a resource does not guarantee a big deposit, and a route across land does not guarantee an easy walk.

Dedicated servers, very slow computers, other TerraFirmaGreg versions and other packs that change world generation are untested.

If a result does not match your world, please include the seed, your settings and an exported report so we can check it.
