Remove HUD From Sequencer Movie

How Do I remove the HUD from my Sequencer Playing? I made a level Blueprint and added the CinematicMode Node with HUD checked. What am I doing wrong?

If you’re referring to the “HideHud” toggle on the LevelSequenceActor, I recently fixed an issue where it was functioning if you autoplayed the sequence. The fix won’t be available until 4.20 though. Are you using autoplay? It might work correctly if you don’t use autoplay.

For tracking purposes, the issue is here (link should be available sometime tomorrow):

At first I used Autoplay function and checked Hide HUD but did not work for me. I thought using blueprint would work.

Is there some documentation on how “HideHud” is supposed to work? It does not hide my widgets added to the viewport so I’m assuming it requires some sort of setup.
Is there a way to detect if the game is running in the “movie recording” sequencer mode, so I can hide my UI manually?

From what I found in code bHideHUD eventually only changes MyHUD->bShowHUD boolean in player controller’s ClientSetCinematicMode() call.
The simplest solution for me was to override this function in C++ and set my own boolean to use it later for widgets. If you are using only blueprints you should look to this bShowHUD boolean in AHUD I guess.
