1:1 Nether

by willocn

1:1 Nether changes the Nether so its coordinates match the Overworld, which lets players travel between the two without rescaling positions.

What it does

The mod replaces the default Nether with a copy whose coordinates are scaled 1:1 against the Overworld. Walking through a portal therefore lands a player at the same X and Z position, which can make the Nether easier to use as a route between bases. The mod encourages travel that uses the Overworld as the main reference. It is published for Fabric, Forge, NeoForge and Quilt, and server owners install it on the server side. Files cover game versions 1.20.3 – 1.21.5, and the code is open source under the MIT License.

Key features

  1. Matching coordinates

    Nether coordinates are mapped 1:1 to the Overworld, so a position in one dimension has the same X and Z in the other.

  2. Dimension override

    The mod replaces the default Nether dimension, so the change applies to the world without a separate dimension.

  3. Overworld-first travel

    Travel between the two dimensions is planned around the Overworld, since positions line up without conversion.

Questions

Does 1:1 Nether need to be installed on the client?

No. Only the server has to run it; a player who joins without the mod still plays normally, so installing it on the client is optional.

What the author says

This datapack makes the nether coordinates 1:1 with the overworld. Encourage using the overworld to travel! It overrides the default the_nether dimension with one that is exactly the same, but with the coordinates scaled 1:1 with the overworld. I haven't tested it with any other datapacks. I suspect it works on…
