Iris is a full featured generator, here is a detailed list of all the features currently supported.
  • NEW! Custom Biomes via Data Packs! You can now give your biomes custom colors for leaves, grass, water & sky!
  • NEW! MCA Pregenerator, Depending on your processor you can turn 15 chunks per second into 90 or higher per second!
  • 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
  • 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
Terrain Features
Iris is a fully featured terrain generator. Terrain features are specific to what Iris is capable of generating
  • NEW! The NOWHERE Noise Generator, looks like the IRIS noise generator but 300% faster!
  • NEW! Iris Jigsaw now allows you to define Villages, Strongholds and even your own custom structures!
  • NEW! Parallax Vacuuming, Allows placed objects to "suck" the terrain up to the bottom of the placed object.
  • Unlimited 3D Biomes
  • Cave Biomes
  • Region Specific Shore, Ocean & Land Biomes
  • Biome Spot & Ridge Overrides
  • Total BlockState abstraction: Define block states fully, not just the types
  • More than 50 noise generator types to choose from (when designing worlds) Simplex, Perlin, Cellular, Static, Fractal FBM to name a few
  • A new type of interpolation, designed for Iris: STARCAST. Take a look here for more details. Bilinear, BiHermite, BiCubic, Starcast & Other tension variants included.
  • 3D Noise Carving
  • Per Biome noise generation with height-bound based interpolation for smoothness instead of raw noise interpolation.
  • Schematics (Objects) up to 512 x 256 x 512 blocks
  • Fully featured structure system which supports infinite structures
  • Support for custom block states (custom block/resource packs)
  • Deposit Generators (Used for ore gen usually). Make deposits of any type and size.
  • Multi layered decorations (decorates caverns caves, under carvings)
Note: Iris needs an internet connection to download dimension projects. If this is not possible, you can download the zip files on https://github.com/IrisDimensions and extract them in the packs folder in Iris.
