Calamity Mod Music

Calamity Mod Music on Your Terraria Server

This mod adds the full Calamity soundtrack plus a music box for every track, and it's a hard dependency for the main Calamity Mod — Calamity won't even launch without it. It can also run standalone, though some music boxes then stay out of reach since they're normally unlocked through Calamity's own content. On your tModLoader server, enable it alongside the main mod in enabled.json; every client needs the matching version or the connection will fail. Resource usage is minimal, since it only ships audio assets rather than new gameplay logic.

Tip: Upload both Calamity mods to your server together and enable them at the same time — the main mod simply won't run without this one.

Plan the rollout and operation

Keep Calamity Mod Music in the same version and update group as the main mod. After enabling it, check the title screen, biome music, and one boss fight with several clients. Because the package can be large, complete downloads before a scheduled group event. Do not remove it separately from a running Calamity installation; test changes together so the hard dependency remains satisfied at server boot.

Before enabling it, back up the world, characters, enabled.json, and mod configuration directory, and record the tModLoader, mod, and dependency versions. Start a world copy with the full list and connect at least two matching clients. Check the core feature, saving, restarting, reconnecting, and, for content mods, world generation or progression. Agree on server-wide settings and reload them after changes in ModConfigs. Update related libraries and content mods together, while adding independent packages one at a time. Before removal, store or discard mod-owned items, NPCs, tiles, and storage structures on a copy; missing content can otherwise damage a world or character. Move to a live maintenance window only after that copy loads without errors. Keep the previous package as a rollback until several sessions have completed successfully. Publish the active list for every player so clients and server do not start with different tModLoader profiles or stale dependencies.
