Multiblock structure rework
A long-running push across GregTech and its addons: more than fifty multiblocks were redesigned, many of them from community design submissions. Every multiblock now names the hatches and casings it is missing instead of just refusing to form.
A machine already standing in your world keeps running. Its old controller still forms the old structure and runs at the same stats. Its tooltip marks it deprecated and points you to NEI for the new controller and the conversion recipe. The "will be removed in next major update" it warns about means 2.10, not this release. For most machines, when you want the new structure you break the old controller, swap it in a crafting table for the new one, and build the new structure.
The structure rework contest
These are the winners of the multiblock structure contest, in which the community designed how each machine should look. The tooltip of each of these controllers names its designer, separately from the machine's author. The controllers you already have keep working, flagged deprecated, until 2.10.0 removes them.

Multiblock Structure Error Diagnostics
When a multiblock fails its structure check, the controller GUI now tells you exactly what went wrong, which hatches or buses are missing, the coordinates of the first incorrect block it finds, and which blocks were expected there instead.

A small clickable button appears next to block errors with coordinates. Clicking it closes the GUI, outlines the problem block in the world in red for 10 seconds and turns you to face it, so you can spot it immediately.

Exothermic Hearth and Endothermic Fridge
The Mega Blast Furnace and Mega Vacuum Freezer are replaced by the Exothermic Hearth and Endothermic Fridge at ZPM tier. Both grow stronger the longer they run - the Hearth gains parallels, the Fridge gains speed - pyrotheum or cryotheum makes either ramp up faster, and both run recipes of any tier if you give them the energy.
A tier 2 Fridge swaps the Frost Proof Machine Casings on the bottom three layers for Infinity Cooled Casing and unlocks Subspace Cooling: 20 L/s of Molten Infinity, Spacetime or Eternity buys one, two or three perfect overclocks respectively, where the Mega Vacuum Freezer burned 2,500 to 7,500 L/s for the same.

The Hearth gains 100K of heat for every voltage tier its combined energy input reaches past MV, so extra energy hatches add heat once they lift the total into the next tier.


Because both machines changed tier, their conversion recipes are assembler recipes rather than crafting-table ones.
Both carry scanner information and Waila integration - heat capacity for the Hearth, Subspace Cooling and the current speed modifier for the Fridge.

optional rebuild - nothing breaks and there is nothing you must do. What you already built keeps running as the deprecated
-Legacycontroller. When you want the new structure, break the old controller, use its conversion recipe to swap it for the new one, and rebuild to the new shape. GT5-Unofficial #6548, GT5-Unofficial #6714, GT5-Unofficial #6478

Industrial Cutting Factory
The Industrial Cutting Factory now requires a sawblade in its controller slot, which sets the machine's parallels, speed, EU usage and how high an energy hatch it will take. There are four, and none of them are consumed or worn down.
| Sawblade | Parallels per voltage tier | Speed | EU usage | Energy hatches |
|---|---|---|---|---|
| Tungsten Titanium Carbide | 2 | 250% | 90% | up to LuV |
| Mysterious Crystal | 3 | 300% | 80% | up to UV |
| Neutronium | 4 | 350% | 70% | up to UEV |
| Transcendent Metal | 6 | 450% | 60% | any tier, and one multi-amp hatch |
The old machine ran at 4 parallels per voltage tier, 300% speed and 75% EU with no blade, so the two cheaper blades are a step down from it. It no longer has a slicing mode; those recipes moved into the cutting recipes.
The blade you fit is the one you see in the machine, and it spins while the machine runs, coasting to a stop at a right angle. A screwdriver turns the render off.

Integrated Ore Factory
The Integrated Ore Factory now processes as many ores at once as its total input power allows, one per 30 EU/t, with no 1024 cap. Each mode keeps a fixed recipe time without overclocks, and batch mode is gone.
It gained laser support, a mode button in its GUI and freer hatch placement, and it no longer needs a maintenance hatch. Its stone dust void now also takes netherrack, end stone, marble and red granite dust.

Zhuhai Fishing Port
The Zhuhai Fishing Port fills its own pond with water once its new structure forms, so it no longer draws water from an input hatch or stops when the pond runs low. Its parallels and modes are unchanged.

Large Thermal Refinery
The Large Thermal Refinery's new structure takes coils and solenoids: every coil tier adds +5% to the speed multiplier and takes another 5% off the power draw, and every solenoid tier adds 2 parallels. That sits on top of the 8 parallels per voltage tier at 2.5x speed and 0.8x EU the machine runs at.

Drone Centre
The Drone Centre now has a camera you can fly. Pick a linked machine in its panel and the view moves to a drone hovering over it, which you fly with WASD, space and shift; aim the crosshair at a machine and the side panels read its status, its progress and what it is producing, and a right-click opens its GUI from where you sit. The drone is a real entity that anyone standing nearby can watch, and the view ends when you steer more than two chunks from the machine you came for.

The panel itself is new too. It lists every multiblock in range of a downlink module, keeps them maintained, and switches them on and off; a production panel with a search bar records what they make, and a machine can sit in several named groups at once. The turn-on-all button clears powerfail events as it goes. A fourth drone tier reaches any downlink set to the same connection key, in any dimension, and a data stick copies a downlink's key.

The drone model was redrawn, bobs in the air, and wears one of four textures for the drone tier in the multi; maintenance has an animation of its own. The new structure takes hempcrete in any color you like.

Planetary Gas Siphon
The Planetary Gas Siphon, which pulls gases out of a planet's atmosphere, got a new and much larger structure, and higher coil tiers now speed it up by 10% each on top of a doubled base speed. It takes batch mode, and its NEI page names the EU/t each planet and depth costs. It also shows the actual pump rate of the Fluids in NEI now instead of some arbitrary number no one understood.

Industrial Arc Furnace
The Industrial Arc Furnace was rebuilt around consumable electrodes and three modes, and almost every arc furnace recipe now needs a programmed circuit: circuit 1 for the plain recipe, which no longer takes oxygen and runs 1.25x as long, circuit 11 for the gas and plasma variants. That goes for single-block arc furnaces and the legacy multiblock too, so automation that pipes oxygen without a circuit stops finding recipes until you add one.
Single-block arc furnaces now draw three times a recipe's listed EU/t. The generated recycling recipes list a third of what they used to, so those cost a single block the same as before. Most other arc furnace recipes kept their EU/t and now cost three times as much on a single block, so check that a bank of them you already run has the supply for it.
An Electrode Hatch holds the electrode, and the electrode is what the machine's stats now come from: fourteen of them, from Graphite up to the Universium nanite, each with its own speed, parallel limit, overclock factors, power draw and durability. Several carry an effect of their own. Netherite shuts the arc down in a single tick, YBCO buys its overclocks with extra wear, and Infinity doubles its parallel target with every run it completes. The three nanite electrodes use a dust of their own material to skip or repair wear. Below a quarter durability, every recipe has a 5% chance of a surge that drops the machine back into ignition.
Normal mode runs arc furnace recipes, ore mode smelts ores straight to molten metal, and EBF mode runs blast furnace recipes at 16 times the recipe's EU/t, with no heat requirement and none of the heat bonuses. Striking the arc takes six seconds, shutting it down another six, and the multi cannot skip tiers. Plasma arc furnace recipes were folded into the main map. Plasma Arc Furnace single blocks you already have were repointed at it and still work, but they can no longer be crafted.

Industrial Centrifuge
The Industrial Centrifuge gathers momentum while it runs, climbing from 2x speed and 4 parallels per voltage tier to 3x and 8, and it spins back down whenever it stands idle. The old machine ran a flat 2.25x with 6 parallels per tier, so it starts slower than before and ends faster. Fifty seconds of unbroken running takes it to full momentum, and twelve and a half seconds of idling loses the lot, so it rewards a line that keeps it fed. The new structure also leaves more room for hatches.

Large Naquadah Reactor
The Large Naquadah Reactor is taller now, has its own casing and new texture. It's also no longer fussy about where its hatches sit: the old tower wanted them all on the bottom layer, any Naquadah Reactor Casing on the new one takes them. It burns its fuels and coolants exactly as it did.

A new overlay texture tells it apart from the Large Chemical Reactor, and Eternal Coils, which could already stand in for the Fusion Coil Blocks, now glow while it runs. Its controller is now made in the Assembly Line at LuV.

Mega Distillation Tower
The Mega Distillation Tower runs distillery recipes now, not just tower ones: 2x speed at half the EU in distillery mode against 1.5x at 90% in tower mode, which is what gives it a use case next to the Dangote Distillus. It moved to LuV, and its height is five steps instead of ten, from 3 output hatches at the shortest to 11 at the tallest. Because the machine changed tier, its conversion recipe is an assembler recipe rather than a crafting-table one.

Mega Oil Cracker
The Mega Oil Cracker's coil discount compounds now: each tier multiplies its power draw by 0.9, where before it was a flat 10% a tier that stopped at half. With Cupronickel coils that is the same as before; from Kanthal to HSS-S it draws more than the old machine, 59% instead of 50% at HSS-G, and from Naquadah up the discount keeps growing instead of hitting a floor. It is a layer taller, and its hatches keep their places: the cracking fluid goes into a middle casing, the hydrocarbon into one side and the cracked output into the other. It moved to LuV, so its conversion recipe is an assembler recipe rather than a crafting-table one.

The Froth Flotation Cell is a wide, shallow basin now instead of a tall tower, with more room for hatches. It now places its own water once the shape forms.

Large Boilers
All four Large Boilers put out 20% more steam, on new structures and new controllers.
Feed a boiler solid and fluid fuel at the same time and it runs at 125% efficiency. The strongest combustion fuels - gasoline, cetane-boosted diesel, high octane gasoline and the jet fuels - now burn in the Titanium and Tungstensteel boilers, which used to refuse all fluid fuel. A boiler that runs out of fuel loses its efficiency gradually rather than all at once. The single-block steam boilers gained a muffler button, and NEI's burn times now match what the boiler actually does.

Algae Farm
The Algae Farm needs power now: exactly one energy hatch, drawing 0.9x the voltage of its tier. That hatch sets the production tier, and your glass tier caps how high it can go.

It runs one recipe at a time, at a fixed duration per tier. The bonus outputs come out 90% of the time. Compost pushes production up a tier. It fills its own pond with water, needs a maintenance hatch and the input hatch can be any tier.
rebuild required - GT5-Unofficial #5608. The steps are on the Before you update page.

Industrial 3D Copying Machine
The Industrial 3D Copying Machine is a good deal bigger, and picks its output three ways. On a regular input bus a programmed circuit selects the variant: circuit N gives the Nth block of the input's chisel group, as NEI lists them. A Chisel Bus holds its targets as ghost items, one, four or nine depending on its tier, and a crafting input buffer uses its pattern's output. ArchitectureCraft blocks go through it now, at their material ratios.

Industrial Coke Oven
The Industrial Coke Oven now grows in slices of heating coils: between 1 and 16 slices, or unlimited with Eternal Coils, and a 2% EU discount per coil tier.
Parallels depend on which casing you build it from, replacing the old fixed parallels and the discount per voltage tier. Heat Resistant Coke Oven Casing gives 16 base and 8 per extra slice; Heat Proof Coke Oven Casing gives 32 base and 16 per extra slice. Infinity Coils and above also allow a single multi-amp energy hatch.

Industrial Sledgehammer and Forge Hammer
The Industrial Sledgehammer runs on Solenoid Superconductor Coils now instead of an anvil: parallels are voltage tier x solenoid tier x 6, with the solenoid tier running from 2 at MV to 12 at UMV, where the anvil gave anvil tier, 1 to 4, x 8. It stands as a tall arch rather than a box.

Infinite Fluid Drilling Rig
The Infinite Fluid Drilling Rig is a much larger structure now that no longer needs mining pipes, and it gains 2 parallels for every energy hatch tier above UHV. It also has a batch mode.

Large Sifter
The Large Sifter stands twice as tall now, with its sieve grates visible through an open frame. The mechanics are unchanged.

Turbines
All five Large Turbines share one shape now, the Supercritical Steam Turbine among them, on the same base as the other four.

The XL Turbines have a structure of their own, and their rotors go into turbine slots in the controller's GUI rather than a rotor assembly. All five variants follow it: Steam, HPSteam, SCSteam, Gas and Plasma.

The turbine shaft moved out of the crafting table into an EV assembler recipe. NEI can dump rotor stats and turbine fuels as CSV or JSON, for use with the Large Turbine calculator.

Ore Washing Plant and Industrial Chemical Bath
The Industrial Wash Plant is two machines now. The Ore Washing Plant keeps ore washing and simple washing; the Industrial Chemical Bath takes the chemical bath recipes onto a structure of its own. Which one an old controller becomes depends on the slot you put it in.

Steam Grinder and Steam Squasher
The Steam Grinder is a layer taller, its sides opened up with frame boxes; the Steam Squasher is a long open frame with a ring of pipe casings around its controller and a press block inside. Both keep a bronze build and a high-pressure steel one, and the mechanics are unchanged. The old shapes still form on the same controllers, so nothing needs converting. The Squasher also accepts input hatches now.

Thermal Boiler
The Thermal Boiler stands as two opposed walls with a containment core between them, a good deal bigger than the box it replaces. Hatches and buses go on either wall; only the maintenance hatch sits in the core. It no longer pollutes and needs no muffler hatch.
