How to Host a One Lucky Block: Skyblock / OneBlock with Dimensions Server

Start with at least 6 GB of RAM — that's the pack's own recommended floor, and it needs to cover five loaded dimensions, the automation mods, and lucky block spawn checks layered on top of the usual single-block progression loop, not just the base OneBlock loop by itself.

Import the modpack straight from its CurseForge/Modrinth project file instead of copying a client's export zip. A clean import keeps the automation mod configs and the per-dimension progression triggers intact, rather than silently dropping client-only files that a hand-exported zip tends to hide.

Watch the console through the entire first boot. A OneBlock-with-dimensions pack like this one has to generate the starting platform and register all 5 dimension transitions plus the automation mod's recipe and network registries in one pass — let every line finish before anyone connects, or you'll end up with a half-built starting block and broken dimension links.

Only invite your group once the log shows a clean, finished startup with no repeated errors. The entire map hinges on one evolving block; if someone starts breaking it while a dimension registry or lucky block table is still mid-load, you can corrupt the one block the whole run depends on.

Take a full world backup before any Fabric loader update, mod version bump, or config change. Losing this world means losing every dimension you've unlocked, every automation setup you've built, and every lucky block roll your group has banked — there's no second starting block to fall back on.
