Immersive Engineering
A highly immersive tech mod that adds realistic industrial machines and multiblock structures.
📖 Introduction
Immersive Engineering (IE) has been developed by BluSunrize and Malte0811 since 2015. Its design motto is 'visible industrialization' — while other tech mods hide automation inside GUIs, IE builds the industrial-era feel out of real in-world structures like conveyor belts, power poles, and smoking chimneys. It's open source under Blu's License (BSD-style) and supports almost every major Minecraft version from 1.7.10 through 1.21.1.
**Five core systems** — multiblock machines (Coke Oven, Blast Furnace, Excavator, and other large structures), a tiered wire network (LV/MV/HV with corresponding power poles), conveyor belts that physically move items, varied power generators (Water Wheel, Windmill, Diesel Generator, Lightning Rod), and the Engineer's Manual guidebook. Each system mimics real industrial infrastructure, so your base gradually starts looking like an actual factory.
What sets it apart from other tech mods like Mekanism or the Thermal Series is that **it prioritizes visuals and atmosphere over speed and efficiency**. Where Mekanism can lay down 2x ore processing in 30 minutes, IE will have you just barely finishing a single Coke Oven in the same time. But that Coke Oven actually puffs smoke, and conveyor belts physically shuttle items past it — the payoff is a scene, not a number. IE has full Forge Energy (FE) compatibility, so it pairs cleanly with Mekanism or AE2 as the industrial-aesthetic layer of a shared base.
In ATM10 it usually fills the supporting role next to Mekanism and AE2, providing the industrial look. In lighter modpack setups — 'vanilla plus a handful of tech mods' — it gets to be the main tech attraction. I've run IE as the main tech mod myself, and the satisfaction of looking at a base that genuinely resembles a factory is something other tech mods just don't quite deliver.
🕒 When to Use This Mod
Pick it up when you want your tech progress to actually look like progress — visible wires, smoking chimneys, conveyor belts you can watch run. The arc from a first water wheel to a fully built coke oven and blast furnace rewards players who like to settle in one base and shape it over many sessions, less so the constantly-relocating type.
📦 Where It Matters Most
In ATM10 it usually plays a supporting industrial role alongside Mekanism and AE2 — a flavor layer rather than the spine. Where it really shines is lighter setups like 'vanilla plus a couple of tech mods,' where it gets to be the main attraction; conveyor belts and pumpjacks reshape the look of a base in a way no other tech mod quite matches.
🎮 How It Changes Your Playthrough
What sets it apart from other tech mods is that your base genuinely starts to look like an industrial site. Conveyor belts physically carry items past you, power lines stretch across hills between your stations, and automation stops being a number on a GUI and becomes a process you can stand inside. It's slower than Mekanism, but the payoff is something you actually want to walk a guest through.
🚀 Getting Started — First 30 Minutes
IE leans on multiblocks, so the entry is a bit slower than other tech mods. That said, following the flow below for the first 60 minutes lands you a Coke Oven, a Blast Furnace, and water-wheel power — and from there the real charm of IE, the 'visible industrialization,' starts to show.
Step 1 — Engineer's Manual and basic tools (10 min)
First priority is the in-game guidebook.
- Craft the Engineer's Manual with 1 leather + 1 book — every piece of IE info lives in this book
- Craft the Engineer's Hammer (iron + stick) — required for multiblock assembly; also rotates, connects, and disassembles
- Craft Wire Cutters (iron + stick) — for cutting and recovering wires
The Manual provides 3D previews for every multiblock, so opening it and copying the diagram block-for-block during assembly almost eliminates mistakes.
Step 2 — The Coke Oven multiblock (15 min)
The first multiblock and the entry point to all of IE is the Coke Oven.
- Craft 27 Coke Bricks (Brick + Sand, etc.) — recipe in the Manual
- Build a 3x3x3 structure following the Manual's 3D preview
- Right-click the center block with the Engineer's Hammer to activate the multiblock
- Feed it coal to produce Coal Coke (high-grade fuel) and Creosote Oil (a liquid fuel)
Coal Coke is required fuel for the late-game Blast Furnace, so most players start with one Coke Oven and scale to 2–3 as needed.
Step 3 — Blast Furnace + Water Wheel power (25 min)
With Coke Oven running, build the Blast Furnace (Steel production) and Water Wheels (early power) in parallel.
- Craft 27 Blast Bricks (Coke Brick + Steel — there's a temporary workaround recipe that doesn't require Steel)
- Assemble the 3x3x3 multiblock and activate with the Engineer's Hammer
- Feed Iron + Coal Coke to make Steel Ingots — the foundation of every late-game IE machine
- Meanwhile, place 2–3 Water Wheels on a riverbank with a Kinetic Dynamo for early FE output
Wiring goes: LV Wire Connector → LV Wire → connector on the target machine, all linked with Shift + right-click. For longer runs, drop in LV Power Poles as relays.
Honestly, my first Blast Furnace took 30 extra minutes because I misplaced a single block — always keep the Manual's 3D preview open and compare block-by-block. That habit alone removes most of the assembly pain.
Where to go next — past the 60-minute mark
- Excavator mining automation: a giant multiblock that mines ore veins automatically — IE's late-game resource line
- Diesel Generator + Pumpjack: oil extraction → refining → diesel fuel → high-output power
- Revolver + Railgun: IE's signature firearms, a different option for late-game combat
- Conveyor belt networks: link Coke Ovens, Blast Furnaces, and storage with conveyors to make a base that actually looks like a factory
Whenever progress stalls, opening the Engineer's Manual covers nearly every answer.
💡 Gameplay Tips
- The Engineer's Manual is the in-game guidebook. Make sure to craft and read it.
- Multiblocks require precise placement. Refer to the 3D preview in the guidebook.
- Connect wires using Shift+right-click.
- The Water Wheel is key to early power generation.
- IE fits players who care about how their base looks more than how fast it crunches numbers. Conveyor belts, exposed piping, and power lines stretching across hills are visuals no other tech mod really matches. Mekanism is faster and stronger, sure — but people who stick with IE to the end almost always say it's because their base finally looks like an actual factory.
⚠️ Common Confusing Points
- • Assembling multiblock structures can be difficult at first. Follow the guidebook diagrams exactly.
- • Different wire types can transmit different amounts of power.
❓ FAQ
What do I make first in IE?
The Engineer's Manual is the top priority. Craft it with 1 leather + 1 book. After that, the Engineer's Hammer and Wire Cutters are enough to start everything else. When assembling multiblocks, keep the Manual's 3D preview open and match blocks one-by-one to avoid the most common mistakes.
Can I use IE with Mekanism? Are the power systems compatible?
Yes — fully compatible. IE supports the Forge Energy (FE) standard, so Mekanism's Universal Cables or AE2's Energy Acceptors will happily accept IE generator output directly. In kitchen-sink packs like ATM10 it's actually standard practice to use IE generators to feed Mekanism machines.
My multiblock won't activate — right-clicking with the Engineer's Hammer does nothing.
Almost always (~99%) a placement error. Re-open the Manual's 3D preview and compare block type, position, and orientation (especially the front face) one cell at a time. The Coke Oven in particular needs exactly 27 Coke Bricks — a single regular Brick mixed in will silently break activation. The block colors are different, so a careful visual scan usually catches it.
How do I keep wires from breaking?
Two main things. First, falling entities (including the player) will collide with wires and snap them — don't run wires over ladders, stairs, or any place you'll cross vertically. Second, each wire tier has a power cap (LV 256 FE/t, MV 1024, HV 4096); exceeding it breaks the wire. If usage grows, upgrade to the next tier.
IE is slower than Mekanism — why would I use it?
Honestly, on pure efficiency Mekanism wins, no contest. The reason to run IE is how your base looks — conveyor belts physically moving items, power lines stretching across hills, smoke rising from a Coke Oven. No other tech mod gives you that. A lot of players stick with IE specifically because 'my base actually looks like a factory,' and I've personally run an IE-as-main playthrough just for that feeling.
