Server vs world config files for Hytale multiplayer — the checklist admins need before friends join or a host panel goes live.

Server vs world config files — the checklist admins share across generators, plus where HySphere tools fit. This Sphere Signal is written against HySphere's live extract (~3,219 items, ~975 creatures, ~2,109 recipes) so the workflow stays tied to real catalog pages.
Community config generators emphasize a root server config.json (name, password, caps, view radius) and per-world config.json under universe/worlds (PvP, NPCs, seed, time).
How to use HySphere for this
Admins and modders lean on raw ids from the same 3,219-item catalog players browse. Display names are for humans; Asset Editor fields want ItemId-style keys.
Prefer Asset Editor / asset packs for data changes (items, NPCs, loot). Reserve plugins for commands and logic. Use HySphere vanilla loot percents as the baseline before custom weights.
Step-by-step checklist
Run this list once, then keep the relevant catalog filters pinned.
- Copy ids from item/creature cards (not just titles)
- Edit loot by nudging vanilla weights 10–20% at a time
- Keep server config.json and per-world configs distinct
- Run MOTD/status/backup chores beside data edits
- Document overrides so future dumps do not surprise you
Pitfalls to avoid
Most wasted hours come from skipping one of these.
- Pasting display names into ItemId fields
- Rewriting entire loot pools in one pass
- Using plugins for pure data edits
- Skipping vanilla baselines from HySphere
Verify on live catalogs
Open the linked tools after every patch week. Sphere Signals are editorial; numbers live on item, creature, and recipe cards.

Frequently asked questions
Item id vs slug?
URLs use slugs; mod forms usually want the raw game id shown on the card.
Asset pack or plugin?
Data → asset pack/Asset Editor; logic/commands → plugin.
How do I balance drops?
Start from HySphere vanilla percents; adjust small deltas and re-test.
Server vs world config?
Root server config covers name/password/caps; worlds get their own files.
Can HySphere edit my live server?
It provides reference data and helper tools — you still apply files on the server.
Seed atlas for admins?
Demand is high; today prioritize loot/item id accuracy from the catalogs.
Does this guide replace the config form?
No — use it as a workflow. The Config form stays the live source of truth for numbers.
