Sable Autonomous Chunk Loader

Sable Autonomous Chunk Loader adds a dedicated chunk-loading block for moving physical constructions created with Sable.

It allows drones, vehicles, ships, missiles, and other physical constructions to continue operating independently, even when no players are nearby.

Features

• Keeps the entire Sable physical construction loaded and ticking.
• Loads normal world chunks around the moving construction.
• Configurable loading radius and update limits.
• Optimized ticket processing to reduce TPS spikes.
• Automatically follows the construction as it moves between chunks.
• Releases all chunk-loading tickets when the loader or construction is destroyed.
• The loader has zero explosion resistance, so explosions can easily disable it.
• Includes a dedicated Creative Mode tab.
• Fixes unstable NeoPeripheral radar coordinates for Sable constructions.
• Supports multiple independent chunk loaders without ticket conflicts.
• Previously disabled loaders automatically recover after updating.

How to Use

1. Place an Autonomous Chunk Loader on your construction.
2. Assemble the construction using Sable.
3. The loader will automatically activate and keep the construction and surrounding chunks loaded.
4. Destroying the loader disables chunk loading for that construction.

Configuration

Configuration file:

config/sable-autonomous-chunk-loader-server.toml

Available settings include:

• Surrounding chunk-loading radius.
• Position update interval.
• Maximum ticket changes per tick.
• Maximum number of unloaded chunks requested per tick.

Large loading radii may increase server load.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.(228-234)
• Sable 2.0.3
• NeoPeripheral 1.4ve or newer — optional

The chunk-loading logic runs on the server, but the mod must be installed on both the client and server because it adds a custom block and resources.
