Utility Nexus Admin

Server administration for NeoForge: global datapack loading, budgeted chunk pregeneration, and alphabetically sorted creative tabs.

Three tools that are individually useful and individually toggleable. Two of them — datapack loading and chunk pregeneration — are things every modpack ends up reimplementing badly with command blocks or scheduled restarts.

The three tools

Global datapack loading. Every datapack in <gameDir>/datapacks/ is injected into every world automatically, client and server alike. No per-world copying, no per-world enabling.

Chunk pregeneration. Pre-generates a radius of chunks with a hard time budget per tick, so it never takes the server below your MSPT target — and it yields when players are online.

Alphabetical creative tabs. Client-side: sorts the creative inventory tabs by the name the player actually sees, in their own language and collation.

Full detail on each: Datapack Loading, Chunk Pregeneration, Creative Tabs.

What makes pregeneration safe

This is the part worth reading before enabling it.

The generator is budgeted, not greedy. Each tick it will spend at most:

	Default	Range
pregen.maxMillisPerTick	8 ms	1 – 40
pregen.maxServerMspt	45 ms	10 – 500
pregen.chunksPerTick	8	1 – 200
pregen.maxConcurrentChunks	4	1 – 64

It stops when either time limit is hit, and it works in bursts with rests by default — 300 seconds of work, then 120 of quiet.

It also yields to players: pregen.workSeconds and restSeconds implement the cycle, and schedule.ignorePlayers decides whether player presence is ignored during the burst.

The design goal is that pregeneration is invisible to gameplay. The defaults are conservative for that reason.

Where to start

• Getting Started — install, and the permission level.
• Datapack Loading — global injection, validation, metadata repair.
• Chunk Pregeneration — every budget, and the schedule window.
• Creative Tabs — the client-side feature.
• Commands and Config — the full /una tree and every option.
• Credits and License.
