1.12 Geode configuration - mickelus/tetra GitHub Wiki

Geodes are dropped when a geode block is destroyed, but the geode block is made to look like regular stone blocks to create the illusion of geodes randomly dropping from stone without allowing the same gameplay as when trying to loot flint from gravel. On which y-levels a geode block can generate, how frequent it generates and which blocks it can mimic can be configured. The metadata of the dropped geode can also be changed, which allows additional geode variants to be added by using resourcepack item models, workbench action configurations and additional loot tables.
