About this Mod

Worldgen Flexiblifier

A tool for making various aspects of Minecraft worldgen more flexible. Meant to be used by mod authors or modpack/datapack
developers. Artifacts are available on CurseForge and Modrinth, or on my maven: https://maven.lukebemish.dev/releases/dev/lukebemish/worldgenflexiblifier/

Features

For more documentation on features, see the wiki.

Dripstone Generation

The vanilla dripstone feature types (dripstone_cluster, large_dripstone, and pointed_dripstone) can now be
configured to place blocks other than dripstone.

Ore Veins

A new feature type, worldgenflexiblifier:ore_vein, has been added, which re-implements the vanilla "large ore veins"
(which contain a filler stone and some ore blocks) so that custom veins can easily be added.

Frequently Asked Questions

Worldgen Flexiblifier server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Worldgen Flexiblifier compatible with fabric and forge and neoforge and quilt?

Worldgen Flexiblifier officially supports fabric, forge, neoforge, quilt for Minecraft 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Worldgen Flexiblifier – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Worldgen Flexiblifier consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
