Pack setup

How should I set up OptiFine for NeoForge for players and a server?

Use OptiFine for 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.

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 OptiFine for NeoForge?

OptiFine for NeoForge. Change the pack release and its contents or setup may change too.

54 mods in this pack file

The selected pack release is OptiFine for NeoForge. That file is for Minecraft 1.21.1 with NeoForge 21.1.170. This NeoForge setup needs Java 21. It contains 54 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.

#UpdateSinytraConnector

Sinytra Connector is the only mod holding this modpack back. It has been stuck on 1.21.1 for over a year now, and it doesn't seem like it's coming back. If anyone can port it, PLEASE do. I had high hopes for this modpack, and I can't do anything until Sinytra Connector updates.
