🚢 Valkyrien Skies 2.0 [UNOFFICIAL]

Build something that moves. No Create required.

Valkyrien Skies brings physics to block-built structures. This unofficial NeoForge 1.21.1 fork, maintained by Kiura, includes fixes for loading, player movement, camera rotation, and interactions with other mods.

Pair it with Eureka 2.0 [UNOFFICIAL] to assemble your own ships and take control at the helm.

🔧 What's included

- Fixes for module conflicts and duplicate command registration.

- Rendering compatibility adjustments for Sodium 0.8.13.

- A fix for the Sable collision conflict that prevented players from properly standing and jumping on deck.

- Improved collision handling that preserves normal movement updates.

- A fix for the camera taking a full turn when crossing the -180°/180° boundary.

- Carry On protection for Eureka's eight helms, using its supported protection tag.

Create is not a dependency. For the ship-building setup, install our Valkyrien Skies and Eureka builds together with the dependencies below.

📦 Getting started

Minecraft: 1.21.1
Loader: NeoForge 21.1.248 or later in the 21.1 series
Java: 21
Required library: Kotlin for Forge

- Install Eureka 2.0 [UNOFFICIAL]

- Install Kotlin for Forge.

Use matching builds on the client and server.

Keep only one Valkyrien Skies JAR and one Eureka JAR installed.

✅ Tested setup

The 1.0.0 builds were tested on NeoForge 21.1.248, with Kotlin for Forge 5.12.0.

Testing covered:

- Ship assembly and loading a saved ship.

- Jumping while standing, sneaking, and sprinting on deck.

- The same movement checks with a saved ship in a full modpack.

- Integration checks with Sodium 0.8.13, Sable 2.0.5, and Carry On.

- Connection and world rendering on a local dedicated server.

🔍 Compatibility notes

Water and aquatic plants can still appear inside ship hulls. Some assembly and visual issues remain under investigation, and large ships can still cause slowdowns.

Carry On must respect the helm protection tag in its configuration. Addons that require the original Valkyrien Skies version numbering may need compatibility updates.

Version 1.0.0 is the fork's release number. “2.0” is part of the project name.
