Hello,

I’m coming across a very unique issue where a bug is only appearing on the packaged game. I cannot recreate the bug in the editor PIE/Standalone.

I am completely stumbled as to how I can debug the error on a packaged game. I have tried to debug via visual studio using this tutorial but it seems to be specific to c++ projects(A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums).

What is the best way to debug an issue for a blueprint project if the bug only appears in the packaged game?

Any guidance on this would be very welcome.

Thank you,

I see my prints in packaged game if I don’t use command

DISABLEALLSCREENMESSAGES.

You can always enable that with

ENABLEALLSCREENMESSAGES.

You got a lot of posibilities of debuging using console.
If you tell what problems I may be able to help.

There is log in files. There is option that displays this log (-log on shortcut of your game as I remember).

Hope that helps.

Thanks for your response Przemek :slight_smile:

I’ve made another question that outlines one of these issues. Any assistance would be greatly appreciated Przemek.

For Blueprint projects, you’re usually limited to logs (Print String, output log), since the built-in debugger doesn’t work outside the editor.

I’ve been working on a tool that lets you debug Blueprints in packaged builds — including remote breakpoints, step execution, and variable inspection.

Might be useful for your case:
