What is Subnautica Aerogel?
Aerogel in Subnautica is a lightweight, translucent crafting material essential for mid-to-late game progression. In the real world, aerogel is a highly porous solid, often dubbed “frozen smoke,” known for its extreme insulation properties and minimal weight. Subnautica’s Aerogel carries this theme into gameplay by serving as a core component for advanced tech and base infrastructure. It plays a vital role in crafting equipment that helps you survive harsher environments and explore deeper biomes.
Key properties:
- Lightweight yet durable material
- Used in high-tech crafting and base modules
Main equipment and upgrades requiring Aerogel include:
- Water Filtration Machine
- Prawn Suit (upgrades and modules)
- Thermal Plant
- Modification Station
Because these items are critical for expanding your underwater capabilities, Aerogel quickly becomes a top priority resource. Understanding where it fits and why it’s needed sets the stage for gathering your ingredients efficiently.
Aerogel recipe and crafting process
To craft Aerogel, you’ll first need to unlock its blueprint in your Fabricator. This unlock typically requires scanning Gel Sacks and Rubies, as well as progressing through initial exploration tasks. Ensure you have collected the necessary data from these sources to enable crafting.
Aerogel crafting recipe:
- Collect 1 Gel Sack
- Collect 1 Ruby
- Use the Fabricator to combine both ingredients
The Fabricator is your primary crafting station, usually located inside your Life Pod or base. Open it, navigate to the Materials section, and you’ll find Aerogel listed once you’ve unlocked the blueprint.
Here is a quick reference table:
Aerogel Crafting Recipe
| Ingredient | Quantity |
|---|---|
| Gel Sack | 1 |
| Ruby | 1 |
By combining these two resources, Aerogel is synthesized—ready to be used in higher-tier crafting and building projects. Mastering this recipe is your gateway to enhancing base filtration, reinforcing structures, and powering Prawn Suit modules.
Where to find Gel Sack and Ruby: Biome & location Guide
1. Gel Sack locations & tips
Gel Sacks grow in several underwater biomes, often sticking out like luminous orbs with a yellowish-green glow. Your best bet for locating these spongy plants includes:
- Deep Grand Reef: Commonly found attached to rock formations at depths between 150m and 300m. Watch your oxygen closely.
- Blood Kelp Zones: Dense kelp forests, where Gel Sacks blend in among the tendrils. Approach carefully to avoid Crabsquids.
- The Dunes: Sandy areas with gentle rolling hills often host clusters of Gel Sacks near natural rock outcrops.
Safety tips:
- Bring a Scanner and Survival Knife for efficient harvesting and blueprint collection.
- Use a High Capacity O₂ Tank if diving deep.
- Beware of aggressive fauna like Warpers and Crabsquids—stay close to vertical surfaces and your vehicle if possible.
2. Ruby Locations & Tips
Rubies, the red crystals essential to Aerogel, are found mostly in rocky outcrops with distinctive red glints. Top locations include:
- Sparse Reef: Shallow, relatively safe biome where Rubies are scattered on large rock faces.
- Grand Reef: More challenging dives with deeper trenches, Rubies cling to the walls and floors here.
- Blood Kelp Zone: Rubies hide among kelp stalks and rocky outcrops amidst hostile creatures.
- Sea Treader’s Path: Open but dangerous; large creatures loom, so beware while mining.
Tips for Ruby collection:
- Scan rock outcrops before mining to check for resource respawn timers.
- Bring Repair Tools or have extra gear for emergencies.
- Use storage lockers or plan inventory space ahead as you collect heavier minerals.
Pro Tips: Sustainable Aerogel Supply (Gel Sack Farming)
Once you’ve harvested your first Gel Sacks, farming them ensures you never run short of Aerogel again. Here’s how to do it sustainably:
- Use a Survival Knife to collect Gel Sack spores from the plant’s mesh.
- Plant these spores in base Growbeds or exterior Planters for safe regrowth.
- Aerogel farming yields improve with multiple Growbeds; spores typically regrow in small cycles.
- Harvest when Gel Sacks are fully grown to maximize your yield.
Farming Gel Sacks removes the pressure of risky wild harvesting and guarantees a steady supply. This stockpile strategy supports continuous crafting and base-building without repeated deep dives.
Pro tip: Always plant more spores than you harvest to maintain a healthy, renewable farm balance—this is your key to stress-free Aerogel production.
FAQ & Troubleshooting: Common Player Challenges with Aerogel
- Can you find Aerogel as loot, or must it be crafted? Aerogel must be crafted from Gel Sack and Ruby. It does not appear as loot or in resource caches.
- Why isn’t Aerogel showing in my Fabricator? Make sure you have scanned both Gel Sack and Ruby fragments to unlock the blueprint. Progressing through biomes also triggers blueprint availability.
- What to do if rare resources seem depleted? Resources like Gel Sack and Ruby respawn over time. Use storage lockers or farm Gel Sacks to ease scarcity. Exploring different biomes may also help replenish supplies.
