How to Host a Liminal Industries Server (Forge 1.20.1 Guide)
Liminal Industries is a Forge 1.20.1 expert pack that layers Mekanism, Applied Energistics, and advanced automation into a structured progression — set in a deliberately eerie, liminal-space world of empty corridors and industrial wasteland biomes. What sets it apart from other tech-expert packs isn't a unique mod selection so much as that unsettling atmosphere, so hosting choices here are mostly about handling automation load, not fighting weird compatibility issues.
Start with at least 8 GB of RAM — that's the recommended floor for Liminal Industries' Mekanism and Applied Energistics automation chains, and it's where to begin before adding any plan headroom for guests or extra machines.
Import the modpack through a clean modpack installer rather than copying files from a client export — Forge 1.20.1 packs like this one break in subtle ways when loader jars or config folders get mixed between client and server builds.
Watch the console through the first boot and don't invite anyone until Forge finishes loading every mod cleanly — Liminal Industries' automation mods generate a lot of startup chunk and data pack work, and errors here are easiest to catch before the world is populated.
Only open the server to players after that first clean startup completes — early joins during a shaky boot are what turn a loading hiccup into a crash loop.
Take a backup before importing an existing world, updating Forge, or changing any Mekanism/AE2 config — a bad import or a config reset can wipe out hours of automation progress that's easy to lose and tedious to rebuild in this pack.

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