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/
For more documentation on features, see the wiki.
The vanilla dripstone feature types (dripstone_cluster, large_dripstone, and pointed_dripstone) can now be
configured to place blocks other than dripstone.
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.
