Immersive Engineering

Overview

Immersive Engineering is a technology mod built around realism-inspired machinery and infrastructure. Rather than compact single-block machines, nearly everything you build is a multiblock structure assembled from specific block patterns and activated with the Engineer's Hammer. Power doesn't flow through glowing tubes; it travels along actual wire cables strung between connectors on wooden posts, giving your base a genuine industrial look.

The mod adds six new ores (Copper, Aluminum, Lead, Silver, Nickel, and Uranium), three voltage tiers (LV, MV, HV), multiple power generators, over a dozen multiblock machines, a conveyor belt logistics system, and several unique tools including a Mining Drill, Revolver, Chemthrower, and Railgun. It uses the Forge Energy system and works standalone or alongside other tech mods. You can browse all items and recipes using the tabs at the top of this page.

Ores and Materials

Immersive Engineering adds six ores to world generation, each spawning at different heights and frequencies. Copper Ore is the most common, spawning in veins of 8 between Y=40 and Y=72 with 8 veins per chunk. Aluminum (Bauxite) spawns in smaller veins of 4 between Y=40 and Y=85. Lead Ore generates in veins of 6 between Y=8 and Y=36, while Silver Ore uses veins of 8 between Y=8 and Y=40 at only 80% spawn chance. Nickel and Uranium are the rarest, both spawning in veins of just 4-6 between Y=8 and Y=24, with Uranium having only a 60% chance per chunk.

Alloys

Two key alloys drive your progression. Electrum is made from Gold and Silver (either as Grit in the Coke Oven or as Ingots in the Alloy Kiln) and is used for MV wiring. Constantan, made from Copper and Nickel, is used in Thermoelectric Generators and certain machine components. Steel is technically an alloy too, smelted from Iron in the Blast Furnace with Coal Coke fuel, and it produces Slag as a byproduct that can be made into fertilizer or Slag Glass for HV components.

Processing Materials

Raw ores can be crushed into Grit (dust) using the Engineer's Hammer early on, or automated later with the Crusher multiblock. Ingots are hammered into Plates, and Plates are cut into Wire with Wire Cutters. These intermediate materials are used constantly: Plates for machine casings and components, Wire for electrical connections and coils, and Grit for alloy recipes and doubled smelting outputs.

Power Generation and Wiring

Immersive Engineering operates on three voltage tiers: Low Voltage (LV), Medium Voltage (MV), and High Voltage (HV). Each tier has its own wire type, connectors, relays, and Capacitors. You cannot directly connect different voltage tiers; use Transformers to step between LV/MV and MV/HV.

Wire Types

Copper Wire (LV) transfers up to 2,048 Flux/t with 5% loss per 16 blocks and a maximum span of 16 blocks. Electrum Wire (MV) handles 8,192 Flux/t with only 2.5% loss per 16 blocks, also spanning 16 blocks. Steel Wire (HV) carries a massive 32,768 Flux/t with 2.5% loss but can span up to 32 blocks. Structural Rope and Steel Cables carry no power but provide physical connections for decoration and the Skyhook zipline. HV wires will electrocute players who touch them; LV and MV wires can be insulated with Tough Fabric (made from Hemp) to prevent this.

Generators

The Water Wheel is the easiest early-game generator. Attach it to a Kinetic Dynamo (base output of 3.0 Flux/t, modified by rotation speed) placed next to flowing water. The wheel applies a 0.75x power multiplier. The basic Windmill uses a 0.5x speed modifier and requires open air, while the improved Windmill with Sail blades reaches 1.0x for full output. The Thermoelectric Generator produces power based on temperature differentials between adjacent blocks (hot blocks like Lava on one side, cold blocks like Ice on the other). For serious power, the Diesel Generator is a 3x5x3 multiblock that outputs 4,096 Flux/t, making it the only native HV power source, fueled by Biodiesel.

Multiblock Machines

Multiblock machines are the heart of Immersive Engineering. Each is built by arranging specific blocks in a precise pattern and then right-clicking the correct block with the Engineer's Hammer. All multiblocks require power delivered through wire connectors placed on specific faces.

Crusher (5x3x3)

The Crusher is one of your first powered multiblocks. It features massive rotating wheels that grind ores into Grit (dust), effectively doubling your ore output when you smelt the resulting dust. It also has a chance to produce secondary outputs from certain materials. The Crusher processes recipes with a default time of 50 ticks modified by the time modifier, consuming energy based on the recipe.

Metal Press (3x3x1)

The Metal Press is a compact multiblock that uses interchangeable Molds to shape metal into different forms: Plates, Gears, Rods, Wire, and more. Each mold is a separate item you craft and place into the press. Processing takes approximately 120 ticks per item with configurable energy consumption. This machine replaces manual hammering for plate production and opens up new material forms.

Arc Furnace (5x5x5)

The Arc Furnace is the largest standard multiblock and one of the most powerful. It smelts ores with a chance to double outputs, processes alloys, and can recycle equipment back into raw materials. It requires Graphite Electrodes (consumable) and accepts up to four additive slots alongside the main input. The Arc Furnace uses significant power but processes items much faster than a standard Furnace.

Excavator (3x7x8)

The Excavator is a massive resource-intensive multiblock with a rotating bucket wheel that extracts mineral veins from underground. It consumes 4,096 Flux/t while operating and draws from chunk-based mineral deposits. Each chunk has a 20% chance of containing a mineral vein with up to 38,400 blocks of resources before depletion. Use a Core Sample Drill first to prospect chunks and find what minerals are available. Mineral types include Iron, Magnetite, Gold, Copper, Bauxite, Lead, Silver, Galena, Nickel, Uranium, Lapis, and Quartzite deposits.

Other Multiblocks

The Fermenter (3x3x3) converts plant matter into Ethanol, while the Squeezer (3x3x3) presses seeds and crops into Plant Oil. Both fluids combine in the Refinery (3x3x5) to produce Biodiesel, the fuel for the Diesel Generator. The Assembler (3x3x3) is an automated crafting multiblock that executes crafting recipes when supplied with the right ingredients and a blueprint. The Bottling Machine fills containers with fluids automatically. The Sheetmetal Tank and Silo provide bulk fluid and item storage respectively as tall cylindrical multiblocks.

Conveyor Belts and Logistics

Immersive Engineering features a full conveyor belt system for item transport that is both functional and visually impressive. The Basic Conveyor moves items horizontally and can be inclined by shift-clicking with the Engineer's Hammer. The Dropping Conveyor has a hatch that drops items downward through floors. The Vertical Conveyor lifts items straight up, and the Splitting Conveyor alternates items between two output directions for load balancing.

The Extracting Conveyor pulls items from adjacent inventories (chests, machines) automatically. Redstone-Controlled Conveyors can be toggled on and off with a Redstone signal. All conveyor types have Covered variants that prevent players and mobs from stepping on them. You can dye conveyors with any color to visually distinguish production lines.

Item Routing

The Item Router block distributes incoming items to different output directions based on filters. You can filter by specific items, Ore Dictionary tags, NBT data, or damage values. Combined with Extracting and Splitting Conveyors, you can build surprisingly sophisticated sorting systems. For bulk storage, the Item Silo multiblock holds the equivalent of roughly 64 chests worth of a single item type, with input from the top and output from the bottom.

Fluid Transport

Fluid Pipes connect machines that produce or consume fluids, like the Fermenter, Squeezer, and Refinery. The Fluid Pump multiblock can extract fluids from the world (water, lava) at a cost of 250 Flux per block. Wooden Barrels and Metal Barrels provide small-scale fluid storage, while the Sheetmetal Tank multiblock handles industrial quantities. Treated Wood Fences form the framework of Fluid Tanks when arranged with a hollow interior.

Tools and Weapons

Mining Drill

The Mining Drill is a powerful fuel-powered mining tool with a 2,000 mB Diesel tank. It accepts interchangeable Drill Heads that determine its performance. The Steel Drill Head has a 3x1 mining area, harvest level 3 (Diamond equivalent), 10.0 mining speed, 7 attack damage, and 8,000 durability. The Iron Drill Head is cheaper with a 2x1 mining area, harvest level 2, 9.0 mining speed, 6 attack damage, and 4,000 durability. The Drill has five equipment slots: one for the head, three for upgrades, and one for a cosmetic Shader.

Revolver

The Revolver is a craftable firearm with an 8-round magazine that accepts multiple cartridge types. It fires with a 10-tick cooldown between shots and can be customized with Shaders for cosmetic variety.

Chemthrower

The Chemthrower is a fluid-powered weapon that sprays chemicals at enemies. It holds 2,000 mB of any fluid and consumes 10 mB per tick while firing, unleashing 8 projectiles per tick in a spread pattern. Different fluids produce different effects: Lava deals fire damage, Potions apply their effects, and various mod fluids may have unique interactions. A focus upgrade tightens the spray pattern from 0.15 to 0.05 spread.

Railgun

The Railgun is an electromagnetic weapon that launches any projectile item at high velocity. It requires a minimum charge time of 20 ticks and consumes 800 Flux per shot. It fires projectiles at 20x base speed and features 8 different zoom magnification levels. Arrows, Graphite Rods, and Steel Rods all work as ammunition, each with different damage outputs.

Skyhook

The Skyhook is a zipline tool that lets you ride along cables strung between connectors. It deals 5.0 base damage and moves at 3.0 base speed along wires, with upgrades available to increase both. It is an incredibly fun and practical way to traverse your base quickly, especially when you have long cable runs between distant structures.

Engineer's Workbench and Blueprints

The Engineer's Workbench is a crafting station for advanced components that cannot be made in a regular Crafting Table. It uses Blueprints, special items that unlock specific recipe categories when placed in the designated slot. The Components Blueprint (crafted with Iron, Aluminum, Copper, Blue Dye, and Paper) unlocks recipes for Iron Mechanical Components, Circuit Backplanes, Vacuum Tubes, and other essential parts used in higher-tier machines.

Other Blueprints unlock projectile recipes (cartridges for the Revolver), specialized components, and more. The Workbench has six input slots, so complex recipes with many ingredients require careful slot management. Some Blueprints like the Arc Furnace Electrode Blueprint can only be obtained from Dungeon Chests or traded from the Engineer Villager, not crafted.

Miscellaneous Content

Faraday Armor

The Faraday Suit is a specialized armor set with very low protection values (1/3/2/1 for Helmet/Chestplate/Leggings/Boots) and zero enchantability. Its sole purpose is to protect against electrical damage from Tesla Coils and HV wires. When the full set is worn, it absorbs low-power electrical shocks. It is not viable as combat armor but essential when working around high-voltage equipment.

Tesla Coil

The Tesla Coil is both a defensive weapon and a decorative showpiece. It passively consumes 256 Flux/t and zaps nearby mobs and unprotected players for 6.0 damage per shock at a cost of 512 Flux per hit. It makes an excellent perimeter defense when powered. Players wearing a full Faraday Suit are immune to its effects.

Industrial Hemp

Industrial Hemp is a crop unique to Immersive Engineering that grows similarly to Sugarcane. When harvested, it produces Hemp Fiber which can be crafted into String (a renewable String source), Hemp Rope Coils for scaffolding and ziplines, and Tough Fabric for wire insulation and Faraday Armor. Hemp seeds are found by breaking Grass.

Decorative Blocks and Lighting

The mod includes Treated Wood variants (fences, stairs, slabs), various metal decorations in Steel, Iron, and Aluminum, and industrial-themed lighting. Electric Lanterns and Floodlights provide strong illumination with an industrial aesthetic. Wooden Posts with arm attachments serve as utility poles for stringing wires. The Balloon is a buoyant light source that floats upward when placed, and comes in all dye colors.

Configuration

Immersive Engineering's config file offers extensive customization. Key settings include ore generation parameters for all six ores (vein size, Y range, veins per chunk, and spawn chance), which can be individually disabled. Machine energy consumption and processing speed have global modifiers. Wire transfer rates and loss percentages are configurable per tier. All bullet damage values can be adjusted individually: Casull (default 10.0), Armor Piercing (10.0), Buckshot (2.0 per pellet), Dragon's Breath (3.0), Homing (10.0), Wolfpack (6.0 base + 4.0 sub-projectiles), Silver (10.0), and Potion Phial (1.0).

The Excavator is highly configurable with adjustable depletion rates (default 38,400 per vein), mineral spawn chance (default 20% per chunk), and digging speed. The Diesel Generator output (default 4,096 Flux/t) and Thermoelectric Generator multiplier can both be tuned. Retro-generation flags allow ores to spawn in already-generated chunks if enabled.
