I made a seed finder for TFC so you don’t have to reroll worlds by hand

I got tired of creating TFC worlds, flying around, finding no tin, and starting over. So I built a mod for it: TerraFirmaScout. It adds a seed finder to the Create World screen. You say what you want near spawn, and it searches seeds until it finds one that fits.

You can pick a starting style (Dream, Easy, Fair, Rugged or Wilderness Start) or build your own wishlist. You can ask for things like freshwater, clay, copper, tin, flux, graphite or kaolin within a distance you're happy to walk. You can also set temperature and rainfall, the spawn biome, surface rocks, forest type, and flat ground for a base.

It checks candidates using TFC's own world generation, and a seed only counts as a match if everything you asked for is confirmed. You can pause or stop whenever you like. Anything it found is kept on a Results screen, along with a few "close calls" that missed one thing, which you can re-check with a bigger search area. It also lets you check a single seed, save seeds with notes, and copy a seed or report to share.

I need help with one thing. I honestly don't know what makes a good TFC seed. The presets are my best guess, and I'd really like input from people who actually play. If you try it, I'd love to hear:

whether a preset's seeds feel like they match the name (is a "Dream Start" actually a dream?)

what you look for in a start that the wishlist doesn't cover yet

any seed where the mod claimed a match and the world proved otherwise. If you can, send the seed, your settings and the exported report.

Heads up, it's still experimental. Very specific wishlists can take ages or find nothing, and in my own tests the harder presets rarely turned up a fully confirmed seed. I haven't tested it on dedicated servers, very slow PCs or most modpack setups. Also, a match doesn't promise big ore deposits or an easy walk between things.

Needs Minecraft 1.21.1, NeoForge 21.1.234+, TFC 4.2.11 and Java 21. It's open source (EUPL-1.2).

Thanks for reading, and any feedback is welcome, even if it's just "this preset is wrong."
