Meccha Chameleon Modded Servers — Connection & Hosting Guide

v2.0.0 Beta Preview: Official dedicated modded server support is a feature introduced in the upcoming v2.0.0 expansion. If you are playing on the live public branch (v1.8.0), modded lobbies can only be joined via the Steam Beta client branches or developer playtest builds.

Community Modded Servers

The community of Meccha Chameleon has driven innovation through custom map creators and gamemode scripts. Previously, joining these custom games required manual file sharing, local folder replacements, and frequent game crashes.

The v2.0.0 server browser overhaul introduces official support for Dedicated Modded Servers. This guide explains how to connect to modded servers, how the automatic client-side file syncing works, security precautions, and how to resolve common lobby connection failures.

1. Connecting to Modded Lobbies

The multiplayer menu has been updated with filters to separate standard rooms from custom-coded lobbies:

Finding Modded Rooms

1. Navigate to Multiplayer from the main menu and select Find Server.
2. Review the lobby list. Modded rooms are marked with a distinct purple gear icon next to the lobby name.
3. If the room name features a red lock icon, it requires a custom password. If Steam invites are failing to connect, refer to our Invite Not Working Fix to bypass using direct room search names.
4. Click Connect to begin the automated handshake.

2. Automatic Mod and Map Syncing

When you click join on a server running mods or custom stages you do not own, the v2.0.0 client manages the download process automatically.

• The Mod Manifest: The server sends a compressed JSON list containing the Steam Workshop IDs of every active map and script package.
• Background Fetching: The game client passes this manifest to the Steam background client. Steam will download the missing .pak asset files directly into your Workshop folder (4704690).
• Verification: Once the downloads complete, the client verifies the file integrity and loads you into the pre-game staging lobby automatically. You do not need to restart the game.
• Reviewing Lobbies: For standard multiplayer onboarding, consult our Play with Friends Guide.

3. Safe Modding and Client Security

Downloading user-generated content (UGC) always carries a slight digital risk. However, the developer has implemented strict sandboxing:

• No Executables: Workshop items cannot package .exe or .dll files. They are restricted to textures, mesh geometries, audio files, and standard engine materials.
• Safe Workshop Sourcing: Never download mods from external web links or file-sharing platforms posted in comment sections. Only use the automatic in-game downloader or subscribe directly via the official Steam Workshop client interface.
• Read our complete Workshop Mod Safety Guide to learn about security checks and preventing malware.

4. Connection Failure Troubleshooting

If you get stuck on an endless “Connecting…” screen or get disconnected immediately after loading, follow this checklist to resolve the issue:

Step 1: Force Update Steam Queue

If a modded server updates their active script package, your local client might be running a slightly cached version. Close the game, log out of Steam completely, and launch it again as Administrator. This forces the Steam client to check the Workshop backend for updates.

Step 2: Clear Stale Workshop Cache

Unreal Engine 5 sometimes fails to overwrite corrupted mod assets.

1. Exit Steam.
2. Navigate to your local directory: C:\Program Files (x86)\Steam\steamapps\workshop\content\4704690\
3. Delete all folders inside this directory.
4. Launch Steam and re-join the server to download fresh copies.

Step 3: Check Firewall Rules

Some modded servers run on custom network ports outside Steam’s standard range. Ensure Windows Defender has not blocked the game client:

1. Open Windows Settings > Update & Security > Windows Security.
2. Click Firewall & network protection.
3. Select Allow an app through firewall and ensure both Private and Public checkboxes are ticked for MecchaChameleon.exe.
