Create Aero Tofu
Physics-simulated airships, floating sky-islands over the void, and in-world computers to fly them. A heavily-patched Create pack built around one idea: earn your wings.
A Create pack that actually flies
Aero Tofu is a NeoForge 1.21.1 pack built around Create and a bespoke, heavily-patched airship layer. You start stranded on a sky-island over the void — and the only way out is to build machines, lay rails, and eventually take flight. It's the pack we run on the Aeronautics server, tuned for a small whitelisted community.
What makes Aero Tofu itself
The load-bearing mods. Everything else hangs off these four.
Physics Assembler
Locks a build into a Sable-simulated rigid body so it can move as one.
Build airships that actually fly
Sable simulates real block-structure physics; Create Aeronautics and Propulsion turn those structures into craft you pilot through the sky. This is the bespoke, heavily-patched heart of the pack.
Portable Engine
Compact, relocatable power — drop it in to drive a contraption anywhere.
Code the machine
CC: Tweaked drops real computers into the world. CC:C Bridge wires them to Create, Avionics lets them fly airships, and KubeJS reshapes the pack’s own recipes. Automate anything.
Adjustable Burner
Tunable heat source for cooking, smelting and fueling the network.
Trains, tubes & maps
Cross the void on Steam ’n’ Rails lines, blast through Hypertubes, and keep your bearings with the Xaero map suite and Create Railways Navigator — airships and trains both show up on the map.
Everything has weight
Sable runs an actual rigid-body simulation on block structures. Stack it badly and it topples; cut a support and it falls. Your airships obey the same rules — which is exactly why building one feels earned.
The Create Galaxy
Create is the hub; ~35 addons orbit it.
The Sky World
Floating islands, roads and structures over a void.
Sights & Sound
Shaders, audio and ambience for the long haul.
Every key worth knowing
Hover any coloured key to see what it does.
Grey caps are vanilla or unbound — the ones marked free are yours to claim. Minecraft stores binds by physical key position, so a US-layout board has the same keys under the same fingers.
Tips, facts & gotchas
The handful of things worth knowing before you dive in.
Shaders ship OFF by default
The render stack is version-locked (the “Sodium 0.8 saga”). Don’t hand-update Sodium or Iris — turn shaders on in Video Settings when you want them.
EMI is your manual
Hover an item and press the recipe key. EMI shows recipes, loot and enchanting — faster than asking in chat.
Proximity voice is installed
Simple Voice Chat is built in. Walk up to a friend and just talk — great for co-piloting an airship.
Wikis, docs & resources
Official docs for the tentpole mods — better than a bare Modrinth page.

🔧 Changes & Tweaks
- Aero Tofu (pack mod) rebuilt — adds the outbound Discord bridge: chat, joins/leaves, deaths and advancements are POSTed to the bot as small JSON payloads, with all formatting handled bot-side. Registered only on a dedicated server, disabled by default and shipping no endpoint, so singleplayer never loads it and nothing is sent until the server is configured.
- Spawn protection disabled —
server.propertiesnow setsspawn-protection=0. Sky Archipelago drops you on a small starter island, and the vanilla default of 16 made that whole island unbuildable for non-ops. - Andesite Jetpack nerfed — speed
0.08→0.04, so it no longer matches the Netherite jetpack. - Sophisticated Backpacks upgrades purged — stack upgrades (all tiers + conversions), XP Pump, Mob Catcher, Advanced Mob Catcher, Battery and Inception upgrades are now disabled pack-wide. Replaces the old catch-all regex with an explicit list, so nothing else gets swept up by accident.
- Sky retune — Cirrus cloud decks moved to y 182 / 272 / 336, lower and upper layers switched to
fancy, and the fog tint now leans on Atmospherics instead of Cirrus's horizon gradient.
🐛 Fixes
- Totems of Undying work again — the death-ragdoll flow intercepted the fatal blow before vanilla ever ran its totem check, so totems silently did nothing. A totem now keeps you on your feet at 1 heart instead of putting you down.
- Absorption hearts are counted — golden-apple hearts were ignored when deciding a hit was fatal, downing (and wasting a totem on) players who would have survived.
- Revive hints — nearby players now get an action-bar prompt naming who is down, and how to get them up with a splash of Healing.
- Fire charges hit airships — Amendments' fire charge flew straight through Sable ship hulls.
- The sky no longer turns white in the rain — Atmospherics' rain/thunder colours are absolute replacements, not tints, and shipped as pure white. Replaced with proper overcast greys.
- Rain falls below the clouds again — Particle Rain's spawn height limit was silently reset to the mod's default by a config-version migration, so rain spawned above the cloud decks. Re-pinned to the lower deck at y 182, which matters constantly here since airships cruise above cloud level.
- Savanna pig texture fixed — Fresh Animations ships the warm pig at the wrong size for 1.21.1, scrambling it. A small Paxi resource pack now supplies a correctly-sized texture.
