Iris World Gen - The Dimension Engine [Build 1.9]

Features
Iris is a full featured generator, here is a detailed list of all the features currently supported.
Support Spigot for 1.14 and up
The Iris Overworld has over 100 biomes, 2,000 schematics & loads of detail. You can view the overworld project at https://github.com/IrisDimensions/overworld
Parallel Chunk Generation + Per chunk multicore chunk gen. Iris takes multicore generation a step further for even more performance.
Optimized Pregeneration allows Iris to pregenerate worlds even faster due to the order of generation & caching!
Fully customizable dimensions with "projects". Make your own biomes, regions, schematics & decorations with ease.
Iris has a "Studio" mode which allows you to design dimensions in schema supported json (autocomplete)
No biome limits
As you design your world, keep flying & see your changes hotload into the generator
Iris cannot cascade, ever! It generates schematics (objects) in a separate region space (memory & storage) then writes only the cross-sections into generating chunks. It's called the Parallax Layer
Fast biome finding with /iris goto
Project downloading & generating from github
