How do I Compare Screenshots in Frontend

Development Programming & Scripting

​​​​​Hello Hello!

I´m trying to compare screenshots using the Automation and Screen Comparison tool in Session Frontend.

I already ran Automation test with the Performance Capture box checked. The test succeeded but according to this tutorial: Screenshot Comparison Tool in Unreal Engine | Unreal Engine 5.2 Documentation I should be able to see my screenshots in the Screen Comparison tab.
What I get is only a file browser but no screenshots pictures.

I’ve set it up as a blueprint actor that inherits from the functional test class.

When I look into the log it looks like the screenshot is being saved:
AutomationFunctionLibrary: Screenshot captured as D://Saved/Automation/FTEST_TEST2_Test.png/Windows_D3D11_SM5_STEREO/NVIDIA GeForce GTX 980 Ti.png

But when I follow the path I don’t find anything.

Do you guys know what I could be missing? Or do you know if there is a better way to compare screenshots in UE4?

Did you manage to make it work? I can’t even find out how to start the Event Start Test. Where sould I place this BP ?
