This mod is a BRDM Mod that allows the nether to generate similar to the Overworld in terms of the height limit.
What Is BDRM?
A BRDM stands for a Bundled Runtime Datapack Mod. It is a type of Minecraft Mod that specifically loads the datapack at runtime. This helps if you are not willing to go through the effort of loading a data pack every time you create a world. Just input the mod into your mods folder and it should be enabled by default.
What is different about the nether?
- Minimum Height is now y=-64
- Maximum Build Height is y=511 (Portals at y=320)
- Upper-Bedrock layer now at y=320
- Lava sea level and bastion spawns have been adjusted accordingly
Any other changes?
Yes, certainly.
- Added 3 new advancements. One of them is a secret.
