NsTut Endless

NsTut

Allows customization or removes build height limits, enabling construction beyond vanilla restrictions.

Endless lets you build higher and dig deeper than ever before. Tired of hitting the build limit? With Endless, you control how tall your world can be — up to Y=8192 and down to Y=-4096.

Features

Extend Build Height — Set your own minimum and maximum build heights. Build towering skyscrapers reaching thousands of blocks into the sky, or dig deeper than the vanilla limit allows.
All Dimensions Supported — Works in the Overworld, Nether, and End simultaneously.
Compatible with Existing Worlds — Apply expanded build limits to worlds you already have.
Works with Forge and Fabric — Pick your loader, the mod works the same on both.
Waystones Compatible — Place waystone blocks anywhere within your expanded build range.
Void Damage at Boundary — Void damage triggers 64 blocks below your configured minimum, giving you safe space to build at the bottom of the world.

Configuration

After launching the game once with Endless installed, a config file is created at config/endless.json. Open it with any text editor to customize:

{
  "buildHeight": {
    "minBuildHeight": -64,
    "maxBuildHeight": 320
  }
}

minBuildHeight — Lowest Y-level you can place blocks (default: -64, minimum: -4096)
maxBuildHeight — Highest Y-level you can place blocks (default: 320, maximum: 8192)

Change the values to whatever range you want, save the file, and restart the game.

Example: Full Height

Want to unlock the full height range? Set both values to their extremes:

{
  "buildHeight": {
    "minBuildHeight": -4096,
    "maxBuildHeight": 8192
  }
}

Recommended Balanced Range

For a good balance of freedom and performance:

{
  "buildHeight": {
    "minBuildHeight": -512,
    "maxBuildHeight": 1024
  }
}

Limitations

Lighting range: Dynamic lighting updates (block light and sky light) are limited to y=-1024 to y=1024 to keep the game running smoothly. Blocks placed far outside this range may appear incorrectly lit. Natural light from the sky still reaches all heights.
Memory usage: Expanding the build height significantly increases memory usage. At maximum settings (Y=-4096 to 8192), each chunk allocates 768 sections instead of vanilla's 24. Allocate more RAM to Minecraft if using extreme settings.
World generation: Terrain generation respects vanilla height rules. Expanded build height gives you more buildable space, but world generation patterns remain unchanged below Y=-64 and above Y=320. Use tools like WorldEdit or datapacks for custom terrain.
