Aluna's Chunk Loaders
Place a chunk loader, right-click it, and pick
exactly which chunks stay active from an in-world map grid. Your farms, furnaces, mob grinders, and
redstone keep running even when you're on the other side of the world (or logged off). Four tiers, a
clean visual picker, per-player limits, and it survives server restarts.
✨ Features
- Pick chunks visually. Right-click a loader to open an in-world grid centered on it. Each cell shows
a live map preview of that chunk's terrain, so you always know what you're keeping loaded. Click to
toggle — green = loaded.
- Real ticking, not just loading. Loaded chunks fully simulate: block entities, crop growth, redstone,
and (optionally) mob spawning — exactly as if a player were standing there.
- Four tiers, from a single chunk up to a 7×7 area.
- Shared access. Any player can open and manage any loader — great for team bases and SMPs.
- Per-player limits. A configurable cap (default 256 chunks per owner) keeps performance in check.
- Survives restarts. Loaders and their selections persist and re-activate when the world loads.
- Polished art. Animated pulsing cores, emissive glow (with Continuity/OptiFine), and full
LabPBR materials (normal + specular) so they shine under shaders.
- No client required for the loading itself — but install on clients too for the configuration GUI.
🧱 The Tiers
| Tier |
Area |
Chunks |
Crafted from |
| Chunk Anchor |
1×1 |
1 |
8× Iron Ingot + 1 Ender Pearl |
| Chunk Beacon |
3×3 |
9 |
8× Gold Ingot + 1 Chunk Anchor |
| Chunk Pylon |
5×5 |
25 |
8× Diamond + 1 Chunk Beacon |
| Chunk Nexus |
7×7 |
49 |
8× Netherite Ingot + 1 Chunk Pylon |
Each tier is crafted by surrounding the previous tier with its material (a ring of 8). The grid is the
maximum area — you choose which chunks inside it are actually loaded.
🎮 How to use
- Craft & place a chunk loader.
- Right-click it to open the chunk picker. The center cell (gold border) is the loader's own chunk.
- Click cells to toggle which chunks stay loaded. The map preview shows the terrain in each.
- Walk away or log off — the green chunks keep loading and ticking.
- Break the loader to release its chunks.

🖥️ Compatibility
- Loader: Fabric. Requires Fabric API.
- Minecraft: separate builds for 26.1.2 and 26.2. Use the file that matches your game version.
- Shaders / resource packs: ships LabPBR
_n/_s maps (Iris/OptiFine) and _e emissive overlays
(Continuity/OptiFine) — entirely optional, ignored in vanilla.
- Performance: force-loading chunks always costs CPU/RAM. The per-player cap is your safety valve;
lower it on busy servers.
🌐 Multiplayer
Server-authoritative: the client only ever requests changes, and the server validates ownership, range,
and the per-player cap before applying. Install on both the server and clients (clients need it for the
picker GUI).
