Which Ultralight release matches NeoForge?

Updated 2 days ago

E4.8.2+1.21.11 NeoForge is a complete pack release for 1.21.11 with NeoForge 21.11.42. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. For this loader, use Java 21. 19 mods in this pack file.

Pack setup

How should I set up Ultralight for players and a server?

Use E4.8.2+1.21.11 NeoForge 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.

Client instance Install E4.8.2+1.21.11 NeoForge
Dedicated server setup Match E4.8.2+1.21.11 NeoForge
Pack loader NeoForge 21.11.42
Java version Java 21

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.

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Ultralight?

E4.8.2+1.21.11 NeoForge on NeoForge. The pack contents and setup notes below stay tied to that release.

19 mods in this pack file

The selected pack release is E4.8.2+1.21.11 NeoForge. That file is for Minecraft 1.21.11 with NeoForge 21.11.42. This NeoForge setup needs Java 21. It contains 19 mod projects. 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.
