How To Add A Web URL To The ULX MOTD In Garry's Mod

Integrating an external web URL into the ULX Message of the Day (MOTD) requires configuring the ULib/ULX server administration module to switch from standard text file rendering to HTML URL mode. By modifying settings within the in-game XGUI menu or editing the underlying data files, server operators can display dynamic web pages, rules portals, or community forums directly inside the Garry's Mod VGUI web frame. Ensuring full cross-browser compatibility requires standardizing HTTP/HTTPS headers and using modern client build architectures such as the x86-64 Chromium branch.

Garry's Mod Server Requirements & Administrative Prerequisites

Configuring a dynamic web-based MOTD within the ULX administration framework demands administrative privileges on the server, basic file structure access, and a web host configured to accept embedded frame requests. Before executing configuration changes, server hosts must ensure their environment meets specific system standards to prevent blank rendering windows or client-side game crashes.

Essential Gear, Access Rights, and System Specifications

• Administrative Privileges: In-game Superadmin status assigned via ULX usergroup management, or direct access to the server host RCON console.
• Core Addon Software: Fully updated instances of both ULib and ULX installed in the Garry's Mod server addons directory.
• Web Hosting Infrastructure: An active web server hosting the target destination page, configured with valid SSL/TLS certificates and permissive cross-origin framing policies.
• File Management Access: FTP or SSH access to the Garry's Mod dedicated server root folder for manual server file configuration.
• Client Architecture Standard: Garry's Mod client installations running either the standard legacy branch (Awesomium engine) or the modern x86-64 branch (Chromium engine).
• Estimated Execution Time: 10 to 15 minutes for basic URL integration and verification across client rendering engines.

Step-by-Step ULX MOTD URL Integration Workflow

Step 1: Launch and Authenticate via the XGUI Administration Interface

To begin configuration without restarting the dedicated server, log into the Garry's Mod server using an account assigned to the Superadmin usergroup. Open the developer console using the tilde key and execute the command xgui or simply type !xgui in the chat window. This launches the ULib Graphical User Interface overlay. If the GUI fails to load, confirm that your SteamID is properly mapped in the ULX users data file and that the ULib core system is actively running.

Step 2: Navigate to the ULX MOTD Module Settings

Once the XGUI menu interface opens on your screen, click on the Settings tab located along the top primary navigation bar. Within the Settings workspace, select the Server tab on the sub-navigation menu, then expand the ULX MOTD options section on the left-hand panel. This configuration panel exposes all internal variables controlling window dimensioning, automated popup toggles, and content sourcing mechanisms.

Step 3: Switch MOTD Rendering Mode to URL Sourcing

Locate the drop-down menu or selection toggle labeled MOTD Mode or Source Type. By default, ULX reads content from a plain local text file located in the server data directory.

1. Change the source drop-down menu setting from File (or Mode 0/Text) to URL (or Mode 1/Web Page).
2. Locate the input field designated as MOTD URL or Web Address.
3. Erase any existing fallback paths and enter the complete target web address, ensuring the protocol prefix is explicitly typed (for example, using full http or https formatting).
4. Check the box labeled Enable MOTD or set ulx showMotd to active to ensure the popup triggers automatically when players complete client authentication.

Warning: Never use target URLs that enforce strict X-Frame-Options headers set to DENY or SAMEORIGIN. Doing so forces the embedded browser inside Garry's Mod to block the web page, resulting in a blank white window for connecting players.

Step 4: Configure Manual Fallbacks in Server Data Files

For administrators operating headless servers or working without XGUI access, the MOTD URL can be defined directly through data configuration files. Connect to your host server using FTP or your server host file manager.

1. Navigate to the path: garrysmod/data/ulx/
2. Open the file named config.txt or motd.txt using a dedicated text editor.
3. Locate the variable definitions for MOTD operation. If editing config.txt directly, update the string line controlling the MOTD generator setting to reflect your desired URL string and set the show mode toggle to enabled.
4. Save the document back to the directory and run the command ulx reload in the server RCON console to apply changes without dropping active player connections.

Step 5: Validate In-Game Rendering Across Browser Engines

After saving your changes, verify that the window renders properly inside the client viewport.

1. Open your developer console and execute ulx showMotd or type !motd in text chat.
2. Confirm that the embedded window loads the target web page completely, including custom CSS stylesheets, fonts, and responsive layouts.
3. Test the interface on both the default 32-bit Garry's Mod client build and the x86-64 Chromium beta branch to guarantee cross-compatibility.

Pro-Tip: Keep web pages lightweight. Garry's Mod VGUI browser instances run on constrained client threads; heavy video backgrounds, unoptimized JavaScript bundles, or large auto-playing media assets can cause severe frame drops or audio stuttering during the player spawn sequence.

ULX MOTD Configuration Parameters & Browser Engine Metrics

The table below outlines technical specifications, console command mappings, and operational thresholds required when embedding external URL content into the Garry's Mod ULX MOTD panel.

Troubleshooting ULX MOTD Web Loading Failures

Scenario 1: Blank White Window Appears When Opening MOTD

• Root Cause: The target website relies on modern SSL/TLS encryption standards (such as TLS 1.3) or modern JavaScript syntaxes that the legacy 32-bit Garry's Mod Awesomium browser cannot interpret. Alternatively, the host web server is issuing an X-Frame-Options: DENY or X-Frame-Options: SAMEORIGIN HTTP response header.
• Actionable Fix: Remove strict X-Frame restrictions on your web server headers for the MOTD page path. If using Apache or Nginx, set CORS headers to allow embedding. For legacy clients, ensure your web server supports fallback TLS 1.2 ciphers or encourage community members to switch to the Garry's Mod x86-64 Chromium client branch.

Scenario 2: MOTD Window Displays Code or Raw URL Text Instead of the Web Page

• Root Cause: The ULX MOTD engine is still set to File Mode (Mode 0) while containing a web address string inside the source configuration file, forcing ULX to render the input string as a local file path or plain text output.
• Actionable Fix: Open the XGUI panel via !xgui, navigate to Settings -> Server -> ULX MOTD, and explicitly change the MOTD Mode dropdown from text to URL. Alternatively, execute ulx motdMode 1 directly in the server host RCON console and execute ulx reload.

Scenario 3: Discord Server Links or YouTube Embeds Fail to Redirect or Play

• Root Cause: Direct web links to platforms like Discord or YouTube often force external application protocol launches or rely on proprietary browser video codecs that standard in-game VGUI web frames block for safety reasons.
• Actionable Fix: Do not set raw Discord invite links directly as the ulx motdURL. Instead, host a simple lightweight HTML landing page containing a styled HTML action button or link. When clicked by the user, this link opens the invitation cleanly or utilizes Garry's Mod internal web hooks to invoke the system default external browser.

Scenario 4: Players Suffer Severe Game Stutter or Audio Overlap Upon Connection

• Root Cause: The web page loaded by the ULX MOTD contains auto-playing video streams, uncompressed audio elements, or heavy script loops that execute automatically during the player connection and entity caching phase.
• Actionable Fix: Optimize the target web page assets. Strip all auto-playing audio tags, disable heavy background media layers, lazy-load images, and condense inline script executions. Keep overall DOM nodes minimal to ensure fast rendering within the client's memory allotment.

Frequently Asked Questions

How do I link directly to a Discord invite inside the ULX MOTD?

You should create an HTML landing page hosted on your web server containing an explicit button or hyperlink pointing to your Discord invite. Direct Discord invite links often fail to load correctly inside the embedded browser frame because Discord enforces security headers preventing external site iframe embedding.

Why does the ULX MOTD reset back to plain text after a server restart?

This occurs when changes are made via in-game console commands without saving the underlying ULib data files, or when server host permissions prevent ULX from writing to the garrysmod/data/ulx/config.txt file. Ensure your server directory file permissions allow write access (chmod 755 or 777), and make changes using the !xgui panel to guarantee persistent saves.

Can I require players to wait a specific duration before closing the MOTD?

Yes, ULX supports enforcement timers within its MOTD options panel. Open !xgui, navigate to Settings -> Server -> ULX MOTD, and set the Minimum Display Time variable to your desired duration in seconds. This prevents clients from closing the web frame until the specified countdown expires.

What is the difference between Awesomium and Chromium in Garry's Mod MOTDs?

Awesomium is the legacy, 32-bit browser framework built into older Garry's Mod installations, which lacks support for modern web scripts, security protocols, and HTML5 video. Chromium is the updated rendering engine available on the x86-64 GMod branch, which handles modern web standards, smooth CSS animations, and complex web applications effortlessly.

How do I change the size and window proportions of the ULX MOTD frame?

Window dimensions can be adjusted directly in the XGUI ULX MOTD server settings panel. Administrators can specify the width and height of the popup window either as pixel dimensions or as percentages relative to the user's screen resolution to ensure full responsiveness across different display monitors.
