About Unlocked Void Sea - Aeronautics Addon

From Modrinth

A simple utility mod that lets you use the "End Sea" physics from Create: Aeronautics in any dimension. Highly configurable.

Unlocked Void Sea

A sable contraption floating in the void sea in the overworld

A simple utility mod that lets you use the "End Sea" physics from Create: Aeronautics in any dimension. It adds the buoyancy, movement resistance, and floating void sea effect to whatever dimension you specify (overworld by default).

Features

Enable the void sea in any number of dimensions at once, each with its own settings
Per-dimension configuration of:
dimension — the dimension id (e.g. minecraft:overworld, minecraft:the_nether)
startY — Y-level where the sea starts (full Minecraft range: -2032 to 2031)
depthGradient — buoyancy ramp strength (0.0 – 10.0)
drag — movement resistance in the sea (0.0 – 10.0)
priority — resolution priority when multiple sources target the same dimension (0 – 10000)
Defaults ship with two entries: minecraft:overworld and minecraft:the_nether
Custom in-game config screen (via Catnip/Ponder) with a dedicated multi-dimension editor
Y-range is automatically clamped at runtime to the dimension's actual min/max to account for height-increase datapacks
Old single-dimension configs are automatically migrated to the new [[dimension]] list format on first load

Config

You can edit settings through the Mods menu in-game (opens the custom dimensions editor) or by editing unlockedvoidsea-server.toml directly. Each dimension is one [[dimension]] block, for example:

[[dimension]]
    dimension = "minecraft:overworld"
    startY = -40.0
    depthGradient = 1.0
    drag = 1.0
    priority = 1000

[[dimension]]
    dimension = "minecraft:the_nether"
    startY = 0.0
    depthGradient = 1.0
    drag = 1.0
    priority = 1000

Add as many [[dimension]] blocks as you like. On dedicated servers you need OP permissions to change settings via the in-game menu.
