How do you get the Processor in Subnautica 2?

The Processor is a base module built with the Habitat Builder. Recipe: 2x Titanium + 1x Mild Acid + 1x Copper Wire. You must first unlock the Habitat Builder.

What does the Processor do in Subnautica 2?

The Processor smelts raw ores into ingots (Titanium Ingot, Copper Ingot, Silver Ingot, etc.), refines materials (Necrolei Cyst → Strong Acid), and processes alternative crafting recipes. It requires 10 energy/second while active.

How much power does the Processor use?

The Processor consumes 10 energy per second while active. Make sure your base has enough power from Solar Panels or a Bioreactor before running it continuously.

What is the Processor queue capacity?

The Processor can queue up to 15 ingredients at once. Load it to capacity before going on a dive for maximum efficiency.

What Is the Processor?

The Processor is a base module (not a hand-held tool) that acts as your smelter in Subnautica 2. Without it, you cannot make Titanium Ingots, Copper Ingots, Strong Acid, or any other processed material — all of which are required for mid-game progression. It is the most critical base module to build early.

Key fact: Building the Processor automatically unlocks the Titanium Ingot recipe in your Fabricator menu.

How to Build the Processor

The Processor is built with the Habitat Builder inside your base. You do not need to scan fragments — the recipe is available from the start once you have the Habitat Builder.

Processor Build Recipe

Ingredient	Quantity	How to Get
Titanium	× 2	Mine from seafloor nodes
Mild Acid	× 1	2x Acidic Raion Pouch → Processor, or find in environment
Copper Wire	× 1	Fabricator (2x Copper)

Power Required: The Processor consumes 10 energy/second while running. Build a Solar Panel or Bioreactor before running large smelting batches or the Processor will stop mid-queue.

Tips for Using the Processor

Build the Processor immediately after the Habitat Builder — it is your second most important base module
Queue capacity is 15 ingredients — always fill it before leaving the base
Build a Solar Panel first to ensure it has power during smelting
The Necrolei Cyst → Strong Acid route (30s) is faster than Sulfur + Gold (60s)
Multiple Processors can run simultaneously — build a second one when your material throughput increases

FAQ

Is the Processor the same as a Fabricator?

No. The Fabricator crafts items from raw materials. The Processor smelts/refines raw materials into intermediate products (ingots, Strong Acid, etc.). Both are base modules.

Where do I get Mild Acid for the Processor recipe?

Craft Mild Acid in the Processor itself: 2x Acidic Raion Pouch → 1x Mild Acid (30 seconds). Acidic Raion Pouches are dropped by Acidic Raions, a small creature found in the early biomes.

Can I use the Processor without a base?

No. The Processor is a base module and must be placed inside a base structure. You need at least a foundation, room, and hatch before you can build one.
