How to Host a Just Create SMP 2 Server
Just Create SMP 2 is the official modpack for Just Create SMP Season 2 on NeoForge 1.21.1 — Create as the core mechanical mod plus a curated set of quality-of-life mods, built for a real server community rather than a generic Create sandbox. Getting the server set up right matters more here than in a solo pack, since a bad first boot affects an entire season of players at once.
Start with at least 5 GB of RAM — that's the floor Just Create SMP 2 itself recommends on its NeoForge 1.21.1 base, since Create's kinetic simulation needs headroom even before any players connect.
Import the official Just Create SMP 2 modpack directly instead of rebuilding it from a client export — a clean server-side import keeps every QoL mod and Create config in sync with what the community actually plays.
Watch the console through the full first boot: NeoForge loading all mods, then Create's kinetic network initializing, before you consider the server ready — mod load errors show up here immediately, not after players connect.
Only invite your SMP season's players once that first boot finishes clean and the world loads without errors — this is the official pack for a real server community, not a solo sandbox, so a shaky first boot affects everyone at once.
Take a backup before any world import, NeoForge update, or config change — losing a Just Create SMP 2 world means losing an entire season's worth of Create contraptions and base progress, not just a single player's inventory.
