This is the datapack version of the original Nether Islands mod. With better noise settings modification support in vanilla Minecraft, it's much easier for you and me to edit the generation!
To edit the datapack, please refer to the GitHub repository's README.
Below is the old description copy-pasted from the mod page, just for reference:
A mod request from a friend to override the Nether's generation and remove the bedrock roof. Designed specifically for Comfy Winter and Better MC Skyblock, but you may include it in any modpack as you want.
I mean, this looks cool as heck (image taken with Oh the Biomes You'll Go)
Configuration
You can configure this mod by editing "config/netherislands.json". It currently only has 2 things to configure though.
- enabled: The global switch of the mod. Default: true
- replacement: The noise generator settings to be used to replace the Nether's original one. Default: minecraft:floating_islands
- noise_override: Whether the mod should override the noise settings. Default: true
- dimension_override: Whether the mod should override the dimension settings. Default: false
- noise_settings: Noise settings to override. This object includes "minY" and "height".
minY: The minimum Y-level of the dimension. Default: 0
height: The world height for the dimension. Default: 256
- dimension_settings: Dimension settings to override.
seaLevel: The sea level (a.k.a. lava level) of the dimension. Setting this to equal or below minY will remove all lava. Default: 0
bedrockFloorPosition: The Y-level of the bedrock floor. Setting this to below minY will remove the layer. Default: -10
The config file should look like this:
Known Incompatibility
- Incendium. The entire generation gets overridden and the bedrock layer is back.
If you have discovered more issues, you may report them on GitHub or join my Discord server.
Note
The 1.19 version of this mod isn't too customizable. Floating Islands generation for the Nether is hard-coded and cannot be changed with config.
