How to change the world seed
The world seed controls how your Hytale world is generated. You can set a seed when creating a new world or change the seed of an existing one to regenerate unexplored terrain.
Hytale seeds only accept numbers. Using letters or special characters will cause the world to fail to load or revert to the original seed.
New worlds
Step 1
Go to the Console tab in your Game Panel and run the following command to create a new world, replacing <name> with your desired world name:
/world add <name>
Step 2
Stop the server from the Console tab. Then go to the File Manager section and navigate to universe/worlds/<your-world-name>/.
Step 3
Open the config.json file and locate the "Seed" field. Replace it with your desired numerical seed:
"Seed": 1234567890,
Step 4
Click Save content at the top right, then start your server from the Console tab.
Existing worlds
Changing the seed on an existing world only affects newly generated chunks. Already explored areas will keep their original terrain unless you delete the chunks folder.
Step 1
Stop the server from the Console tab. Then go to the File Manager section and navigate to universe/worlds/<your-world-name>/.
Step 2
Open the config.json file and change the "Seed" field to your new numerical seed:
"Seed": 9876543210,
Step 3
Click Save content, then go back to the world folder and delete the resources folder. This forces the server to regenerate terrain with the new seed.
You can also delete the chunks folder if you want to remove all existing terrain and start fresh with the new seed.
Step 4
Start your server from the Console tab. Explore new regions to see the new world generation.
FAQ
Why is my seed not working?
Make sure you are only using numbers. Letters and special characters are not supported. Also ensure the server was stopped before editing config.json.
Why are my chunks still the same after changing the seed?
The new seed only applies to newly generated chunks. To explore new terrain, travel to regions you haven't visited before. If you want the entire world to be regenerated, stop the server and delete the chunks folder.
How do I teleport to a specific world?
Use the /tp world <world-name> command in-game with admin permissions. To list all available worlds, run /world list.
✅ That's it! Your server will now generate new terrain using the updated seed. If you have any problems, contact us via Discord (opens in a new tab) so we can help you.
