Configuring Cynosure Mod for Multiplayer and Dedicated Servers

When playing on a multiplayer server with custom Kotlin mods, Cynosure Mod handles critical background communication between the server and connecting players.

Matching Server and Client Files

Because Cynosure provides network codecs and networking rules, it dictates how custom game data travels across the network. If a server uses mods that rely on Cynosure, the library must be installed on both sides:

1. Add Cynosure to the server's mods folder alongside any dependent mods.

2. Ensure every connecting player also has Cynosure placed in their local client mods folder.

3. Make sure both sides use compatible loader platforms, whether running on Forge or Fabric environments.

Diagnosing Connection and Sync Issues

If players experience sync issues, missing custom blocks, or immediate disconnections when joining, verify that the networking rules can function properly:

• Confirm that the network codecs are matching on both client and server installations.
• Check that no dependent mod was added to the server without also giving it to the client.
• If custom data fails to transfer, restart the server so Cynosure can re-read and package data safely across all connected players.
