About this Mod
Superflat Features and Structures
This mod allows any structure and feature to generate in any super flat preset, structures are still limited by other spawn conditions such as biome, and mineshafts needing to be underground.
Note this mod also makes trial chambers spawn less often as when generating above ground as in most super flat presets they were cluttering the sky, but this will also apply to non super flat worlds, this mod is mostly meant for pack makers making super flat expriences
For just structure generation see https://modrinth.com/mod/superflat-structures
If you want features without structures simply disable structures on world creation
