Loader Fabric 0.16.14

Pack setup

How should I set up Ultimate Realism for players and a server?

Use Ultimate Realism 1.0.6 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 Ultimate Realism 1.0.6

Dedicated server setup Match Ultimate Realism 1.0.6

Pack loader Fabric 0.16.14

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 Ultimate Realism?

Ultimate Realism 1.0.6. Change the pack release and its contents or setup may change too.

36 mods in this pack file

The selected pack release is Ultimate Realism 1.0.6. That file is for Minecraft 1.21.5 with Fabric 0.16.14. It contains 36 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.
