Quick answer
Which Cave Horror Project 1 release should I use?
Cave Horror Project 1 v3.4.1 is a complete pack release for 1.20.1 with Forge. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. Could not safely read this pack file.
Pack setup
How should I set up Cave Horror Project 1 for players and a server?
Use Cave Horror Project 1 v3.4.1 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.
What are the server requirements for Cave Horror Project 1?
Cave Horror Project 1 v3.4.1. Change the pack release and its contents or setup may change too.
The selected pack release is Cave Horror Project 1 v3.4.1. That file is for Minecraft 1.20.1 with Forge. 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.
