Satisfactory World Seed Guide

Satisfactory seeds do not generate a new map. Terrain, caves, spawn areas, crash sites, geysers and node positions are fixed.

A seed only changes randomized assignments on existing points. To reproduce a layout, share all three settings:

World seed
Resource Node Randomization
Resource Node Purity

Quick Facts

Default randomization keeps the original resource layout.
Randomized modes assign resources to existing node slots.
Purity controls extraction rate.
The seed range is -2147483648 to 2147483647 (4294967296 different seeds per configuration).
The seed finder shows the best seed found so far, not a guaranteed perfect seed.

Resource Node Randomization

This setting controls which resource each existing node slot can become.

Mode	Effect
`Default`	Uses the original Satisfactory resource layout.
`Random`	Shuffles the normal resource distribution across valid node slots.
`Basic Resource Rich`	Biases more nodes toward Iron, Copper, Limestone and Coal.
`Advanced Resource Rich`	Biases more nodes toward Caterium, Quartz, Sulfur, Bauxite, SAM and Uranium.
`Fossil Fuel Rich`	Biases more nodes toward Coal, Crude Oil and Sulfur.

Resource wells can change assigned resource in randomized modes. Geothermal geysers stay geothermal.

Resource Node Purity

Purity changes extraction rate.

Purity mode	Effect
`Default`	Keeps the normal purity setup unless randomization remaps it.
`All Impure`	Forces adjustable nodes to impure.
`Mostly Impure`	Shifts purity downward.
`Average`	Forces adjustable nodes to normal.
`Mostly Pure`	Shifts purity upward.
`All Pure`	Forces adjustable nodes to pure.
`Random`	Randomizes adjustable node purity using the seed.

How The Finder Ranks Seeds

The finder tests Satisfactory seed candidates against your current settings.

Ranking order:

Target priority: Critical, then High, then Normal.
Matched targeted nodes.
Fully satisfied target groups.
Selected Resource priority totals in your drag order.

Use targets when location matters. Use resource priority when total output matters.

Search Tips

Choose the world mode first. A target may be common in Advanced Resource Rich, rare in Random, and impossible in Default.

Start with the nodes that define the layout. Add more targets after you find a promising seed.

Use priorities strictly:

Critical for required clusters.
High for important support resources.
Normal for nice-to-have placement.

Let specific searches run longer. The exact layout you want may not exist, and checking the true best seed can take days.

Share the full setup, not just the seed number. The same seed with different modes is a different layout.
