Details

Portal Transit and Reliability

Immersive Portals Visual Compatibility

• Added optional Immersive Portals visual compatibility.
• The Immersive Portals inspired visual style is only available when the Immersive Portals mod is installed.

Requirements

• Minecraft 1.21.1

The same Rift Gun version must be installed on both the client and server.

There are no required runtime dependencies other than NeoForge. JEI, RyoamicLights, and Immersive Portals integrations are optional and are not bundled in the release JAR.

Immersive Portals is only required if you want to enable the optional Immersive Portals inspired portal visuals.

Known Issues
