WHAT IS INTEGRATED CATACLYSM?

    Integrated Cataclysm is the fourth mod in the Integrated Structures series. Not only does it completely overhaul L_Ender's Cataclysm structures with tons of heavily detailed dungeons to explore, but it integrates Supplementaries/Quark decorations and Create mod doors, puzzles, traps. It also has a handful of recipe changes further integrating the mods.

Configuration and optional Integration:

By default Integrated Cataclysm overhauls some of Cataclysm's recipe as well. You can change this using this datapack.

To change spawn rates change the spacing and separation in the structures sets. Spacing is the Average distance between two neighboring generation attempts. Value between 0 and 4096
Separation is the Minimum distance in chunks between two neighboring attempts. Value between 0 and 4096. Can't be bigger than spacing

To improve compatibility with other structure mods, add structure SETS to the “structure set to avoid” list in each of the tags/worldgen/structure_set files

 
Features and Planned features:

Added details and features to all of Cataclysm's structures. 

Some recipe changes integrating Create mechanical crafting, mixing, etc
