About this Mod

Angel Islands

This worldgen datapack adds floating islands above the world's oceans whilst also retaining regular land generation!

By default, islands are fairly frequent yet scattered over the oceans. They are found only in the deepest section of oceans, typically around mushroom islands.

You could consider this pack a mix between regular worldgen and my other datapack, Aetherial Islands.

Notice:

The default foliage (trees, grass, flowers, etc.) typically would spawn on the highest surface block. I have modified them so that they can spawn on any level, so if an island is above an island, its shadow doesn't block trees from spawning on it. This also results in slightly different tree placement in the rest of the overworld.

Also checkout

  • Skylands over the Sea a mod that replaces the void in Aetherial Islands with an infinite ocean.
  • Aetherial Islands: Clusters Edit an add-on that creates zones where islands will and won't generate, creating large gaps between island clusters (works for Angel Islands as well!).
  • Diabolical Islands a mod that brings the Aetherial Island generation to the Nether!

IMPORTANT:

Versions below 2.0.0 of the datapack/mod alter the dimension height for versions 1.20.5 due to an unremoved experimental file. This was added at first to add more breathing room for building on the islands, but I have since removed it in 2.0.0+, as this will corrupt worlds when the mod is removed. 2.0.0 does not have this issue. If you are migrating a 1.X.X pack to 1.21.9+, please use version 1.0.3, but note that it will not be supported for future versions. I apologize for any inconvenience.

Compatibility: Does this work with insert mod name here?

If that mod changes the terrain (e.g. Tectonic), one of the mods will probably overwrite the other. If that mod adds biomes (e.g. Terralith), it should be compatible, but if you have issues with bodies of water not generating, use the optional dependency, Lithostitched. This is just because of the tricky technique I had to use to make this, along with Minecraft's weirdness with surface builders. Some issues may need specific compatibility packs made, which I may make in the future.

Thank You to...

If you enjoy this pack, thank Nekomaster for making most of the modrinth page for me, and Iulian for originally commissioning me for this modification.

Angel Islands officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.10, 1.21.9, 1.21.8. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Angel Islands – how to optimize performance?
