How to Host a TerraFirmaAdventure Server

TerraFirmaAdventure takes TerraFirmaCraft's geology-driven survival — rock knapping, ore prospecting, and a slow metallurgy progression — and gives you somewhere to actually go with it, layering in dungeon mods and custom structures on Forge 1.20.1. That combination makes it heavier to boot and generate than plain TFC, so getting the RAM floor and first-boot checks right matters more than usual. This guide covers the setup steps specific to this pack, not generic Forge advice.

1

Start with a server plan that gives you at least 7 GB of RAM — that's the floor TerraFirmaAdventure needs once TFC's chunk-heavy terrain generation and metallurgy simulation are running alongside the pack's added dungeon and exploration mods. Going lower is the fastest way to end up with chunk loading stalls the moment someone leaves spawn.

2

Install TerraFirmaAdventure through CoalHost's modpack importer rather than zipping up your client folder — the importer pulls the exact Forge 1.20.1 build and mod list the pack author shipped, so you don't end up running a stale or mismatched version against your client.

3

Watch the console through the first boot: TFC's world generation is slower than vanilla because it's simulating rock layers, ore veins, and climate zones, and the adventure layer adds its own structure generation on top of that. Let it finish loading completely — look for the 'Done' line — before assuming anything is wrong.

4

Only invite players once that first boot has completed cleanly and the server has stayed up for a few minutes under no load. Pulling people in mid-generation on a TFC-based pack risks corrupting the chunks they spawn into.

5

Take a backup before any world import, Forge update, or config change. TFC progress is slow to rebuild — rock knapping, ore prospecting, and the metallurgy chain take real hours — and the dungeon and exploration content layered on top means a bad rollback can also cost explored structures and loot, not just a smelted ingot.

Use a cleaner TerraFirmaAdventure path

CoalHost is built around modpack hosting, which makes TerraFirmaAdventure much less annoying to launch correctly.
