Why Matinee can't record UMG UI?

Greetings, I got part from my UMG UI working and would like to record a video showing it working, but the Matinee recording feature is not showing it.

More Info:

  • To “spawn” the UI I’m using the BeginPlay>CreateWidget>SET>AddToViewport BP pipeline as shown on the docs.
  • The resulting video just shows the level and the game working, but I can see the UI “influence” since looks like everytime I interact with the slider the game lags/pause (a problem to further analysis).
  • The Widget is displayed correctly on the “recording window”, just isn’t being captured.

I suppose that Matinee can just record what is drawn on a HUD Actor/Class, but I have no idea how to encapsulate the widget inside my HUD Class.

Thank you.
