Diabolical Islands x Incendium

by VictusFC

Diabolical Islands x Incendium makes Incendium's biomes and structures generate on the floating islands that Diabolical Islands creates, following that mod's island rules.

FabricForgeNeoForgeQuiltServer-side onlyMIT License1.20 – 1.21.11

What it does

The compatibility mod connects two worlds. Once Diabolical Islands is installed, Incendium's biomes and structures spawn on its sky islands instead of the standard terrain. The author describes the work as tweaking noise generation and structure spawn conditions so the two mods stop conflicting, a fix that had been missing until this release.

Diabolical Islands and Incendium Legacy are both required, and the server and any player need both installed for the islands to generate. Incendium Translation Fix is optional and listed as a recommended addition for the Incendium text. The mod runs on the server only, so players join without installing it, and it is published for Fabric, Forge, NeoForge and Quilt. It is released under the MIT License and is not open source. Files exist for 1.20 – 1.21.11, with 1.0.1 for 1.21.11 as the latest build.

Key features

  1. Incendium biomes on sky islands

    Incendium's biomes and structures generate on the floating islands produced by Diabolical Islands.

  2. Island-based spawn rules

    Structure placement follows the floating island rules of Diabolical Islands rather than standard surface generation.

  3. Adjusted noise generation

    Noise generation and structure spawn conditions were tweaked so both mods can generate together.

Questions

Does Diabolical Islands x Incendium need Incendium Legacy?

Yes. Incendium Legacy is a required dependency, so it must be installed alongside this mod and Diabolical Islands.

Does the server need this mod installed?

Yes. Only the server needs it, and players join without installing anything.

Is Incendium Translation Fix needed?

No, it is optional. The author recommends it for the Incendium text, but the mod works without it.

What the author says

Incendium Translation Fix is optional, but I highly recommend it. After the release of Create：Aeronautics, I started looking for skyblock-style mods. Create: Aeronautics really got me excited. Eventually, I found mods like Aetherial Islands, Diabolical Islands, and more—they perfectly matched my vision for sky islands!
