Pack setup

How should I set up The Solar Apocalypse for players and a server?

Use Season 2: 23.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Pack loader Fabric

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Season 2: 23.0 on 1.21.5 Fabric. The pack contents and setup notes below stay tied to that release.

Could not safely read this pack file

The selected pack release is Season 2: 23.0. That file is for Minecraft 1.21.5 with Fabric. We could not safely count the mods in this release. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

about

Everything was in perfect balance — the flora thrived, the fauna followed their natural rhythm. Until one day, the SUN began to act strangely. Each sunrise seemed brighter, hotter… BIGGER. Why is the SUN changing? What should you do? ~~Who will survive?~~

The Solar Apocalypse is a challenge-focused modpack designed to take you on a difficult and ever-evolving survival experience. Inspired by elements of Project Zomboid, it reimagines Minecraft with new threats, a harsher environment, and new behaviors that force you to adapt.

On day 5, the Sun ignites every surface block. By day 10, anything exposed begins to burn. From day 15 to 100, its heat consumes the world layer by layer—descending from height 100 until reaching layer 0. For versions below 27.0+beta, click here.
