AeroPortals

Sail your Create: Aeronautics airship through a Minecraft or Modded portal and the whole ship goes with you. Players, passengers, decorations, and more travel together. AeroPortals is the bridge between Create's airships (Sable physics) and Minecraft's portal system.

Warning

Sable is a deeply intrusive physics mod and stability is never guaranteed. Always back up your worlds before using this mod. If something goes wrong, please report it on our issue tracker with logs and a reproduction case. We will do our best to accommodate new feature requests alongside bug fix updates.

What it does

• Nether portals Fly your airship into a nether portal and you and the ship arrive on the other side. Wide ship? Build a wide portal. AeroPortals matches the source portal's dimensions at the destination, generates one if needed, and clears a safe landing area so you don't end up entombed in a wall of basalt.

• End portals Sail onto an end portal and the ship lands on the obsidian platform in the End. If the platform was destroyed (or you're in a custom End) AeroPortals rebuilds it before you arrive. Travelling back from the End drops you near world spawn.

• Aether portals (when The Aether is installed). Same idea as nether portals but with glowstone frames and the Aether dimension.

• Ars Nouveau warp portals (when Ars Nouveau is installed). Use a Warp Scroll to configure the portal's destination, then fly your ship into it. The ship lands on top of the configured warp position.

• Draconic Evolution portals (when Draconic Evolution is installed). Build a Dislocator Receptacle portal with a configured Dislocator and fly your ship through. The ship lands on the receptacle's stored target.

• Pina colada teleport (when Tropicraft is installed). Drink a pina colada while sailing your airship and you and the ship travel to the Tropics. Drink another in the Tropics to come home.

Who comes with you

When the ship teleports, these passengers come along:

• Players standing on the ship
• Decorations and storage: paintings, item frames (and what's inside them), armor stands, all minecart variants, block/item/text displays
• Functional bits: Create seats and contraptions, Create: Aeronautics propellers and sails, Botania mana/corporea bursts, snow golems, leash knots

These do NOT come along:

• Mobs (cows, zombies, villagers, ...)
• Dropped items
• Projectiles, falling blocks

This matches what already happens when you fly your ship around normally: those entities fall off. The portal teleport behaves the same way.

Want cows on your airship?

Drop in a one-file datapack at data/sable/tags/entity_type/retain_in_sub_level.json:

{
  "replace": false,
  "values": [
    "minecraft:cow",
    "minecraft:villager",
    "minecraft:wolf"
  ]
}

Multiple datapacks merge cleanly, so several mods can add to this tag without stepping on each other.

Commands

/aeroportals teleport <dimension> (op only)

OP-level command (permission level 2). Teleports you and the airship you're riding to the named dimension. Autocompletes the dimensions available to your server:

• overworld, nether, end always
• aether when Aether is installed
• tropicraft when Tropicraft is installed
• You can also type any custom dimension as namespace:path directly

The ship lands at a sensible spot in the destination: the obsidian platform for the End, somewhere safe above the surface for everything else.

For server admins

Config

config/aeroportals-server.toml is generated on first server launch.

Key	Default	What it does
detection.scan_interval_ticks	5	How often the mod checks if your airship is touching a portal (in server ticks; 20 = 1 second).
detection.verbose_logging	true	Log each teleport at INFO level. Turn off for quieter logs.
detection.max_sublevel_aabb_volume	200000.0	Skip teleporting any ship larger than this volume. Sanity guard so a wildly-misconfigured ship doesn't trigger a teleport.
teleport.portal_cooldown_ticks	200	After teleporting, the ship is locked out of portals for this long (in ticks). Prevents a ship from immediately re-teleporting back through the destination portal.
teleport.dest_portal_search_radius	128	How far AeroPortals looks for an existing matching portal at the destination before deciding to build a new one.
teleport.generate_matching_portal	true	If false, the teleport aborts when no destination portal is found instead of building one.

Crash safety

AeroPortals writes the ship snapshot to disk before moving it. If the server crashes mid-teleport, the ship is recovered on next startup instead of being lost.

Known limitations

• Ropes and joints don't survive teleport. Ships connected by Sable rope/docking links travel together and stay in formation, but the physical connection itself breaks. Re-tie the rope or re-dock at the destination.
• Other modded portal types aren't auto-supported. Twilight Forest, Mystcraft, etc. aren't recognized. Vanilla nether/end, plus Aether, Ars Nouveau, Tropicraft, and Draconic Evolution are the supported portals today.
• Speed slightly drops per teleport. Each portal trip costs about 10% of your velocity (Sable's reload setting). Tune sub_level_velocity_retained_on_load in Sable's config if you want full preservation.

Want support for another portal or dimension?

Open an issue on the GitHub issue tracker. We're open to adding support for additional portal mods and custom dimensions: just let us know which mod you'd like to see and we'll take a look.

For mod developers

AeroPortals fires SubLevelTransferEvent on the NeoForge event bus after each teleport, with the new SubLevel, source/destination dimensions, and translation vector. Useful if your mod tracks cross-SubLevel positions (for example, docking pairs, partner references) that need updating after a move.
