How to Host an Omnifactory Server
Omnifactory is the original GregTech Community Edition automation pack on Forge 1.12.2 — it established the "GregTech-lite" formula that standard Forge mods get folded into, before its community fork Nomifactory CEu expanded on it with more content and better balance. Getting the launch right matters either way: enough RAM for the integrated progression, a clean modpack import, and a verified first boot before anyone starts building toward end-game automation.
Start with 6 GB of RAM unless this is a very small server — Omnifactory's own recommended floor, since the GregTech progression and the Forge mods folded into it carry real overhead beyond a plain Forge 1.12.2 pack.
Use a proper modpack import flow instead of guessing from a client export, so the Forge version and every integrated mod match the official Omnifactory release exactly.
Watch the first boot logs until the server finishes loading on 1.12.2 and all the integrated GregTech-lite content registers cleanly before anyone logs in.
Invite players only after that first clean startup — a half-loaded GregTech progression is a bad place to start building machines.
Take a backup before world imports, loader updates or config changes — losing an automation chain you've built toward the pack's GregTech progression is a bad night.
Use a cleaner Omnifactory path
CoalHost is built around modpack hosting, which makes Omnifactory much less annoying to launch correctly.
