Solarpunk Pig Guide: Truffles, Shelters, and Happy Pigs

Pigs are one of the most rewarding animals you can raise in Solarpunk. Keep them happy and they drop truffles passively over time, which feeds directly into your crafting and food progression. The system is straightforward once you understand what pigs actually need, but there are a few mechanics that trip up new players and cost them time. This guide covers everything from shelter setup to automatic feeding so your pigs stay productive without constant attention.

Pig shelter placement basics

What do pigs produce in Solarpunk?

Happy pigs produce truffles, which drop beside the pig shelter over time. Truffles don't appear in your inventory automatically; they collect in the food basket attached to the shelter. Check the basket regularly to pick up what your pigs have generated. If the basket fills up and you haven't emptied it, production effectively stalls, so building the basket collection loop early is worth doing.

The key word throughout the pig system is "happy." Pigs that have their needs met (food, water, and shelter) are the ones generating truffles. Neglect any one of those needs and output drops.

How to set up a pig shelter

The pig shelter serves two purposes: it gives pigs a place to sleep and protects them from rain. Both matter for keeping happiness up. Build the shelter before you bring pigs to an island, then position your feeding trough and water trough nearby.

Animals automatically stay close to a feeding trough as long as it has food in it, which makes trough placement the real anchor point of your setup. Put the feeding trough within range of the shelter and your pigs will naturally cluster in the right area.

Water trough options

You have two water trough types available for pigs:

The standard trough fills at 0.2 water units per tick during rain, so if your island gets regular rainfall you can go a long time without manually refilling. The powered version removes the manual step entirely by drawing from the ground via your energy network, which is the better long-term option once you have energy infrastructure in place.

How does animal feeding work?

The feeding trough holds food for pigs and keeps them anchored nearby as long as it's stocked. Animal feed is the food item you load into it. Running out of feed is the most common reason pigs stop being happy, so keeping a supply of animal feed on hand matters more than almost anything else in the pig care loop.

For a more hands-off approach, unlock the Automatic Feeder through the automatic animal-care research path. This powered feeder handles restocking without you manually loading the trough, which is a significant quality-of-life improvement once your farm scales up. Check the Solarpunk farming guide for crop priorities that feed directly into your animal feed production.

How to breed pigs in Solarpunk

Breeding pigs requires a few specific conditions to be met at the same time:

• You need two pigs of the same species on the same island
• Both pigs must have all their needs fulfilled (food, water, shelter)
• Each pig needs its own shelter to have its needs fully met
• There must be an available shelter nearby for the offspring

That last point catches a lot of players off guard. If you only have two shelters for your two breeding pigs, there's nowhere for a new pig to go, so breeding won't trigger. Build a third shelter before you expect offspring, not after.

How to move pigs between islands

The animal transport system lets you relocate pigs to any island you choose. The process works like this:

1. Place an Animal Receiving Station at the destination island where you want the pig to arrive
2. Use the Animal Transporter tool on the pig you want to move
3. The pig travels to the receiving station you designated

You can also lead pigs manually by holding their favorite food; they'll follow you as long as you're carrying it. The transporter is the cleaner option for moving animals across islands, especially once you're managing multiple locations.

For more on building out your resource network across islands, the Solarpunk resources guide covers how Silicon, Cobalt, and other materials tie into your broader progression.

What research unlocks pig farming?

The Animal Basics Pack in the Research Table is the starting point for the entire animal system. Unlock it early to access shelters, troughs, and the foundational animal care tools. The automatic animal-care research path builds on top of that with the Automatic Feeder, which is worth prioritizing once you have a stable energy network.

If you're still working through early progression, the Solarpunk beginner's guide walks through the Research Table and early unlock priorities in detail.

Pig care at a glance

The pig system rewards players who set it up properly once and then leave it mostly alone. Automate feeding and water, keep a spare shelter available for breeding, and check the food basket often enough that it doesn't cap out. That's the whole loop.
