Install mods (Forge/Fabric)
Run Forge or Fabric mods on a Victus server — put mods in the mods folder, match the loader/version, and install the same mods on your client.
Mods change the game itself and require a modded server type — Forge or Fabric — set by your server's egg. Unlike plugins, most mods must be installed on BOTH the server and every player's client, and the versions must match exactly. Mixing Forge mods with a Fabric server (or vice versa) will not work.
Fabric mods only run on a Fabric server; Forge mods only on Forge. Check each mod's page for the loader AND the Minecraft version before downloading.
Set the loader, then add mods
- Make sure your server runs the Forge or Fabric egg. If not, switch software (this may require a reinstall — back up first).
- Open the Startup tab and confirm the Minecraft version and loader/build match the mods you want.
- Open the Files tab and go into the
modsfolder (create it if it does not exist). - Upload each mod .jar into
mods(use SFTP for a whole modpack — it is far faster than the web uploader). - Restart from the Console tab and watch the log for load errors.
Install the same mods on your client
- Install the matching Fabric/Forge loader in your Minecraft launcher for the same MC version.
- Put the same client-side mods in your client mods folder.
- Join the server — a mismatch usually shows as a "missing mods" or handshake/connection error.
For a known pack (CurseForge/Modrinth), use its server pack if provided, then upload the whole mods folder via SFTP. Modpacks need much more RAM than Vanilla — if it crashes on boot, check "Out of memory / server keeps crashing".
