About this Mod
Unlocked Void Sea

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:-2032to2031)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:overworldandminecraft: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.
