Three rows in the Speeds group of World settings control production. Assembler speed (AssemblerSpeedMultiplier) is how fast assemblers craft. Assembler efficiency (AssemblerEfficiencyMultiplier) is how many items a blueprint needs: higher values need fewer. Refinery speed (RefinerySpeedMultiplier) is how fast refineries and furnaces process ore. 1 is realistic, and 3 means “times three”. Change them with the server stopped.
Change production speed
- Choose Stop and wait for Offline.
- Open the Config Editor and choose World settings. A new server shows that tab only after two starts: see the world settings guide.
- Scroll to the Speeds group (1).
- Type a number in Assembler speed, Assembler efficiency or Refinery speed.
- Choose Save, then Start. The game reads the new values as it starts.
- Speeds group
Each row takes a number from 0.1 to 1000. Keen Software House, the game’s makers, give 3 for each of the three when a world file does not hold the setting. The game’s own screens offer Realistic and a few steps such as 3 and 10, and Keen’s dedicated server tool takes 1 to 100. A number below 1 is outside what that tool allows. The panel accepts any number in its range, but Keen says values outside what its tools allow are not tested and not officially supported. Start with 3 and see how it plays.
What each row does
- Assembler speed: how fast assemblers build components and tools. It does not change what a blueprint costs.
- Assembler efficiency: how many items an assembler needs for a blueprint. A higher number means fewer items. It does not change how fast the assembler works.
- Refinery speed: how fast refineries and furnaces turn ore into ingots.
None of the three rows has a help line in the panel. The labels and this list are the whole explanation.
If it does not work
- Save is greyed out. The server is not offline. Stop it first.
- Nothing changed in game. The row only applies after a start. Check the server was started after you saved.
- Production feels too fast or too slow. Change the number, save with the server stopped and start again. You can try 2 or 5 as steps.
- Items cost less, but crafting is not faster. That is Assembler efficiency. Raise Assembler speed for faster crafting.
See the world settings guide for every other row.
