Advanced Game Logging (GLS) – In-Game Log Viewer for Shipping Builds (UE5 Plugin)

Everything works fine in PIE.

You package the build… and suddenly things start breaking for no reason.

No Output Log.

No console.

Nothing useful on device.

Now you're stuck doing things like:

• Connecting ADB

• Pulling logs manually

• Asking QA “what exactly happened?”

• Adding random print strings and rebuilding again and half the time… you’re just guessing

• GLS basically gets rid of that whole mess.

What GLS Does

GLS gives you a real-time log viewer directly inside your running game.

No external tools.

No PC connection.

No switching windows.

Just press ALT + SHIFT + G and instantly see your logs – even in Shipping builds.

Built for Real Debugging Scenarios

• Bugs that only appear in packaged builds

• Mobile & VR debugging without cables

• QA testing without developer dependency

• Multiplayer debugging with isolated logs

• Tracking runtime state, flags, and edge cases

If you've ever said:

“It works in editor but breaks in build” – this is for you.

Why Developers Use GLS

Because traditional logging breaks exactly where debugging becomes hardest:

• Packaged builds

• Real devices

• Multiplayer sessions

GLS restores runtime visibility, where it actually matters.

Who It’s For

• Unreal Engine developers

• Mobile / VR / console teams

• QA testers

• Teams debugging Shipping builds

Key Features

• On-device logs — view logs directly inside the game on phone, VR headset, or console without any PC connection

• Shipping build support — debug Shipping builds in real time without ADB, console commands, or external tools

• In-game overlay — open logs instantly during gameplay or PIE without switching windows

• Smart filtering — isolate logs by category, verbosity, class, object, function, tags, network role, or PIE instance

• GLS_LOG macros — structured C++ logging with tags and context, available in Shipping builds

• PrintStringToGLS — Blueprint-friendly logging with custom colors, fully Shipping-compatible

• Custom Named Tabs — save separate views for AI, UI, networking, gameplay, and more

• Persistent UI — filters, tab layouts, and sizes are saved between sessions

• Session Log Files — automatic log files with configurable formats, available even in Shipping builds

• Multiplayer-ready — isolate logs per client, role, PIE instance, or controller

• Cross-platform — works on PC, mobile, consoles, and VR/AR

• Zero setup — works in Development, Test, and Shipping

• Optimized and production-ready — proven in large UE5 projects with heavy logging

• Per-object isolation — quickly focus on logs from a specific actor or object during gameplay

Actively used in the development of a large-scale Unreal Engine project with heavy runtime logging.
