Sable: Everything Everywhere All at Once (Aeronautics Addon)
by Ranold
Sable: Everything Everywhere All at Once keeps every Sable sub-level loaded, including the ones a world has never loaded, so airships stay active once they are present.
What it does
The addon changes how Sable's sub-level loading system forces chunks to load. Without it, Sable keeps sub-levels loaded only near loaded chunks, and the rest are frozen in storage on disk. With it, sub-levels stay loaded at all times, and sub-levels that were already saved are woken up and unfrozen when the world loads. The addon also includes parts of the world a player has ever visited.
The addon is meant for use alongside a larger render distance mod, such as Distant Horizons, Voxy or Separate Sable Render Distance, which is an optional dependency. Sable itself is required and must be installed first. The mod is published for NeoForge 1.21.1 only, and it is server-side only, so players join without installing anything. Its source code is open source under the MIT License.
Key features
Constant sub-level loading
Sub-levels stay loaded all the time, so an airship that was built once remains active without needing a nearby player.
One-time world scan
A command reads Sable's saved sub-level data and loads everything in the world at once, taking a few seconds to complete, with the time rising as the world grows.
Toggle gamerule
The forceloadAllSublevels gamerule switches the behavior on or off, with the default set so the mod's loading applies.
Throttled scan
The scan is spread across ticks instead of done in one step, so the server is not frozen while it runs.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Requirements
Dependencies declared by the latest file for each loader.
Required 1
Optional 1
Use cases
Large airship fleets
Players with many airships spread across a world can keep all of them active without visiting each one.
Who it’s for: Server owners who run Sable airships and want every sub-level kept loaded, and players on those servers who use a render distance mod.
How it compares
Sable Sub-level Loading System Fix is a client and server fix under the MIT License that also simplifies sub-level loading, but it is not open source. Sable: Maced is server-side only, open source under the GNU General Public License v3.0 only, and targets NeoForge 1.21.1, so it covers a different part of the setup. Disable Sable Button is client-side only and open source under the MIT License, so it works on the client alone.

What the author says
Sable: EEAAO is a lightweight modification to Sable's sub-level loading system, intending to simplify forceloading sub-levels. It's designed to be used with a further render distance mod like Distant Horizons or voxy, and SSRD Without the mod, Sable only keeps sub-levels loaded while the chunks around it are loaded…
