Hollow

by Spirit Studios

Hollow fills in several world-generation features that Mojang once promised but never shipped, and players who want those extras can add them to a Fabric or Quilt world.

What it does

Hollow adds features described by its author as the promises Mojang made about hollow logs and other world content that did not reach the game. Installation covers the server and each player's game. Fabric API is required, and a dynamic lights mod can optionally be added alongside it. Builds cover 1.20.1 – 1.21.4 on Fabric and Quilt, with 1.3.2 as the latest file for 1.21.4.

Key features

  1. Hollow logs

    Hollow logs generate in the world as a new natural log variant with an open interior.

  2. Missing world content

    Additional generated features are added to the world, in line with the promises the author lists.

  3. Quilt and Fabric builds

    The same feature set is published for both loaders, so either can be chosen per world.

Questions

Yes. Fabric API is a required dependency, and it must be installed alongside Hollow.

Does Hollow work on Forge or NeoForge?
