Use this Data pack to adjust the biome weights for the two existing biomes!

The instructions for how to edit/use this pack are provided below. If you have any questions - feel free to join my discord and ask me!

THIS IS ONLY FOR V1.3.3 OF LUMINOUS: NETHER!!!

How to use:

1.) Unzip/extract the provided zip file to wherever is most convenient, I would suggest your desktop

2.) Navigate through the folders as follows: data/luminous_nether/blueprint/modded_biome_slices/ until you see two json files - "ash_forest_slice.json" and "fungal_plains_slice.json"

3.) Open either of them with a text editor , like notepad. When opening, you'll be met with code that looks like this:

{
  "levels": [
    "minecraft:the_nether"
  ],
  "weight": 3,
  "provider": {
    "type": "blueprint:multi_noise",
    "biomes": [
      {
        "biome": "luminous_nether:ash_forest",
        "parameters": {
          "temperature": [-0.2, 0.5],
          "humidity": [-1.0, -0.5],
          "continentalness": [-0.5, 1.2],
          "erosion": [0.5, 1.68],
          "depth": 0.0,
          "weirdness": [-0.82, 0.6],
          "offset": 0.0
        }
      }
    ]
  }
}

By changing the number highlighted in yellow, you can adjust how common or rare the biome is. The default weight is 3. There is one json for each biome, and their weight works independantly of the other.

4.) Once you have made the changes, f
ind your "%appdata%" folder on your device (I recommend using the windows searchbar if you don't know how to do that)

5.) open your ".minecraft" folder and find the "saves" folder

6.) Locate the file with the world name that matches the world you wish to edit

7.) drop the WHOLE "Luminous_Nether_Tweaks" master file (Zipped or unzipped - up to you!) in the "datapacks" folder!

(Note: A restart is NOT required for these changes to take effect on a server! The server operator just has to type "/reload" in the console once the data pack is properly placed in the data pack folder!)
