Pack setup
How should I set up OptiSup [Client] for players and a server?
Use 1.12.2_forge 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.

Dedicated server setup Match 1.12.2_forge
Pack loader Forge 14.23.5.2864
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.
Referenced mods 12
Client only 2
Server only 0
Not labelled 10
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 OptiSup [Client]?
1.12.2_forge on 1.12.2. The pack contents and setup notes below stay tied to that release.
The selected pack release is 1.12.2_forge. That file is for Minecraft 1.12.2 with Forge 14.23.5.2864. It contains 12 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.
