Click on More World Options...
Click on Import Settings
Select world-settings.json
-template from the downloads
directory in your Survive Create Prosper 4
installation.
If you want to customize the seed of the world which will be generated from this template, you need to edit world-settings.json
before using the Import Settings
feature.
To do so, open world-settings.json
in your text-editor of choice and edit every entry with the "seed":
-prefix.
This files was made possible thanks to the Oh The Biomes You'll Go To community and their discord. They have a pinned message in their #general channel which tells you how this is achieved. I merely adopted it, changed it so it works with my modpack and now use it myself.
In case you do not have the mentioned file in your downloads
directory, here's a copy of it for you:
