Guides, tutorials, and tips for Terraria server hosting.
tModLoader is on Terraria 1.4.4 and PC-only; the vanilla server is on 1.4.5.8 and the one Re-Logic’s crossplay plan points at. The facts side by side, why worlds do not cross over, and how to decide for your group.
Journey is a world difficulty fixed at creation, and fifteen journeypermission keys decide who may freeze time, use god mode or slide the difficulty. What 0, 1 and 2 mean on a dedicated server, and which powers to lock on a shared one.
Every serverconfig.txt key from the official 1.4.5.8 zip — world, autocreate, difficulty, maxplayers (1–255), port, password, worldrollbackstokeep, secure, npcstream, the fifteen Journey permissions — plus the command-line flags that duplicate them.
One .wld file: where worlds live on Windows and Linux, getting one out of Steam Cloud, placing it where worldpath points, why the name is the identity, and the two moves that do not exist — from tModLoader, and from a console.
Only two sourced figures exist: 500 MB for a small world (Terraria wiki) and at least 768 MB (Pelican egg README). What drives memory — world size first, players second — what nobody has measured, and how we size 2, 3 and 4 GB plans.
Not today, on any setting. What works now (PC and mobile on the same version), what Re-Logic plans for consoles in 1.4.6 Crossplay Phase One, why a fixed IP and port matter, and how to be ready the day it ships.
Re-Logic’s Crossplay Phase One, in its own words and with dates: consoles typing an IP and port, the “same release version” rule, what is still unsaid, and what a dedicated server has to be ready for on 1.4.6 day.
The official terraria.org server zip, a serverconfig.txt walk-through, TCP 7777, the exit-saves rule and the version-matching trap that breaks joins after every patch — the full Linux setup, from Re-Logic’s own downloads and the zip itself.
