NovoAtlas

by TheDeathlyCow

NovoAtlas is a data-driven world generator that builds Minecraft terrain from images, with the Atlas approach as its base.

What it does

Instead of the vanilla terrain shape and biome placement logic, NovoAtlas replaces them with its own generator that reads image-supplied maps. Biome maps, a set of datapacks and a repository wiki describe how to use it, and the wiki explains how to create custom worlds and dimensions. Example datapacks ship with the mod, and further examples are available from the releases page. The generator supports custom biomes in the dimensions it creates, and the mod affects only dimensions created with its generator.

NovoAtlas requires Fabric API and a Mapbox API key. Its builtin patch works with TerraBlender surface rules, and most biomes, decorations, structures, features and surface rules work with its dimensions. Some noise features, such as custom terrain cave shapes, do not. The mod is server-side only and is open source under the GNU Lesser General Public License v3.0 or later. Its releases cover 1.20 – 26.3, with Fabric, Forge, NeoForge and Quilt files, and snapshot builds are published.

Key features

  1. Image-based terrain

    A world can be shaped from images, with biome maps defining where each biome sits across the generated dimension.

  2. Datapack creation

    Datapacks that add images can be copied from the example set or written from scratch, with the wiki describing each step.

  3. Biome and structure support

    Biomes such as Biomes O'Plenty generate appropriately in NovoAtlas dimensions, and most structures and surface rules carry over.

  4. Improved generation

    Recent builds add structure-terrain blending, better underwater cave generation and a set of minor biome map fixes.

Questions

Does NovoAtlas need Fabric API?

Which loaders does NovoAtlas support?

NovoAtlas has files for Fabric, Forge, NeoForge and Quilt, and its latest builds target 1.21.1.

Does NovoAtlas need to be installed on the client?

No. Server owners install it, and players connect with no copy of their own.

Are all vanilla structures and noise features supported?

Most are. Some noise features, such as custom terrain cave shapes, do not work with NovoAtlas dimensions.
