🌟 What is GregTech Nexus Addon?
GregTech Nexus Addon (GTNA) is a feature-rich addon for GTCEu Modern that adds a full progression layer on top of the base mod. It introduces wireless steam and energy networks, 12+ multiblocks, custom hatches with unique mechanics, exclusive materials, and a developer API compatible with KubeJS and the GTCEu Java API.
Whether you're building a megafactory powered entirely by solar steam, automating parallel recipes across dozens of machines, or scripting entirely custom multiblocks through KubeJS — GTNA has the tools.
📡 Wireless Steam Network
Say goodbye to spaghetti pipe networks. GTNA's Wireless Steam Network lets you transmit steam across your entire base without a single pipe connecting boilers to machines.
- Wireless Input/Output Hatches link machines to the steam network
- Huge Steam Buses for mass item throughput
- Full integration with AE2 autocrafting pipelines
- Works seamlessly alongside GTCEu's native steam machines

⚡ Nexus Flux Matrix — Wireless Energy (v0.2)
The Nexus Flux Matrix is a massive, scalable multiblock that acts as the central energy bank for your entire factory — no cables needed.
- Size: 3×7×7 (min) up to 31×7×7 (max), up to 750 Capacitor blocks internally
- 14 Capacitor tiers from LV (160K EU/block) up to MAX (5E EU/block)
- Quadratic capacity scaling: the more blocks, the bigger the bonus
- Efficiency from 85% (LV) to 100% (MAX)
- Transfer limit up to 500 ZEU/t
- Cross-dimension support (ZPM+)
- Safe Mode: automatically cuts output below 10%, restores at 25%
- Comes with Wireless Energy Hatches, Wireless Dynamo Hatches, Receiver/Transmitter Covers, and the Quantum Network Terminal for real-time monitoring

🧵 Custom Hatches & Parts
GTNA introduces a family of specialized hatches that extend GTCEu's multiblock system with brand-new mechanics:
Thread Hatch — Allows a multiblock to run completely different recipes simultaneously. Recipe A and Recipe B can process at the same time in the same machine.
Accelerate Hatch — Reduces recipe duration (ticks) directly, without increasing energy consumption per tick.
Overclock Hatch — Applies extreme overclock multipliers on top of GTCEu's standard electrical tier overclocking.
Advanced Parallel Hatch — Scales parallels far beyond what the standard hatch allows.
Wireless Steam Hatches — Connect any steam multiblock to the wireless steam network.
Huge Steam Buses — Massive item input/output for high-throughput steam setups.

🧪 Custom Materials
GTNA adds unique alloys, elements, and fluids with real roles in the tech progression:
- Stronze — Early-game structural alloy
- Breel — Mid-tier conductor material
- Echoite — Resonance-based exotic element
- Supercritical Steam variants — High-efficiency power fluid
- Additional custom elements and compounds across all tiers

🔧 Hydraulic System
A pressurized fluid processing system built around the Steam Manufacturer. Enables steam-era assembly-style crafting for modpack progression without requiring electricity.

🔌 KubeJS Integration (v0.2)
Starting with version 0.2.0, GTNA provides full KubeJS compatibility via soft-dependency. Modpack developers can create advanced multiblocks using all GTNA custom hatches directly from scripts — no Java required.
GTCEuStartupEvents.registry('gtceu:machine', event => {
event.create('my_machine', 'gtna:multiple_recipes')
.recipeType('gtceu:assembler')
.pattern(definition => FactoryBlockPattern.start()
// ...
.or(Predicates.abilities(GTNAPartAbility.THREAD_HATCH).setMaxGlobalLimited(1))
.or(Predicates.abilities(GTNAPartAbility.ACCELERATE_HATCH).setMaxGlobalLimited(1))
.or(Predicates.abilities(GTNAPartAbility.OVERCLOCK_HATCH).setMaxGlobalLimited(1))
)
.gtnaConfig(config => {
config.maxThreadMultiplier(2)
config.overclockBonus(0.1)
})
})
The gtna:multiple_recipes factory type automatically wires up WorkableElectricMultipleRecipesMachine under the hood — Thread, Accelerate, and Overclock Hatches work out of the box.

🛠️ Java API
GTNA exposes a full Java API for addon developers:
- Create multiblocks that natively support all GTNA hatches
- Register custom materials and fluids using the GTNA material builder
- Extend the wireless steam/energy systems
- Hook into Thread/Accelerate/Overclock hatch behavior
📖 API Overview →
🔌 AE2 Integration
GTNA is designed with AE2 autocrafting in mind:
- Wireless Steam Hatches work seamlessly with AE2 pattern providers
- Huge Steam Buses accept ME interface connections
- All GTNA multiblocks are fully compatible with ExtendedAE setups
- Recommended setup guides included in the wiki
