More Nether Mod
This mod is a BRDM solution that fundamentally changes the vertical limitations of the Nether, bringing them in line with Overworld standards.
What is BRDM?
The abbreviation BRDM stands for Bundled Runtime Datapack Mod - a Minecraft modification that automatically loads a data pack during game startup. This eliminates the need to manually install a datapack every time you create a new world. Simply place the mod file in the mods folder, and it will start working immediately.
What changes await players in the Nether?
The lower generation boundary now drops to level y=-64, while the maximum building height reaches y=511. The bedrock ceiling has been raised to y=320, and portals also generate at this altitude. The lava sea level and bastion spawns have been adapted to the new conditions.

Additional Features
The mod includes three new advancements, one of which is hidden and unlocks under special conditions.
// Portal height check code
if (portalY >= 320) {
activateHighPortal();
}
Compatibility
This modification is incompatible with other Nether world changes - both mods and datapacks that alter Nether generation. Requires Fabric Language Kotlin to function.
