Multiplayer
For Multiplayer 1.14.4:
- Open the server.properties file found in the same folder as your server
- Add use-modded-worldtype=islands at the end of the file
- Save it
- Make sure the server doesn't already have a world generated, this only works when first generating the server's world!
For Multiplayer 1.15.2:
- Open the server.properties file found in the same folder as your server
- Replace level-type=default with level-type=islands
- Save it
- Make sure the server doesn't already have a world generated, this only works when first generating the server's world!
For Multiplayer 1.16.5 and 1.17.1:
- Open the server.properties file found in the same folder as your server
- Replace level-type=default with level-type=islands:islands
- Save it
- Make sure the server doesn't already have a world generated, this only works when first generating the server's world!
Will this work with other mods that add new biomes ?
In almost all cases yes! As long as you choose the Islands world type registered biomes added by other mods will spawn as islands. As with everything however there are exception where mods implement their biomes differently or lock them to their own world types and we can't do anything about that.
