About this Mod

Seeded Dimensions -

This mod simply adds in a config to set the seed per-dimension.

Config

// Located at config/seeded-dimensions.json
{
  "minecraft:overworld": "default",
  "minecraft:the_nether": "default",
  "minecraft:the_end": "default"
  // "NAMESPACE:DIMENSION": 2
}

You can add any dimension to this list, use "default" to use the default config file seed, or set a number for a custom seed.

If you run /execute in ... it will auto-fill what dimensions exist, that tag shown is the tag that should be in the config here.
