Superflat Features and Structures
by VirtualSofia
Superflat Features and Structures lets structures and features generate inside superflat worlds, for pack makers who build flat-world experiences on NeoForge.
What it does
Structures and features that normally depend on biome can generate in superflat presets, which the vanilla settings do not allow. Some structures, such as biome mineshafts that need to sit underground, still follow their own spawn conditions and stay limited. The mod also reduces how often trial chambers spawn, since they tend to appear above ground in most superflat presets and clutter the sky.
The mod is built mainly for pack makers who design superflat experiences. Structure generation can be turned off in world creation for players who want the features without any structures. It is released under the MIT License and its source code is public. The files target 1.21.1 only, with 1.1.0 as the latest NeoForge file, and it runs on the server side alone.
