Hello,
There has to be something really silly as to why this is not working. The basic set-up is that I created a Cinematic Event placed on MyPlayerController. I feed the MediaSource through this CustomEvent, then its routed to the OpenSource node as per the screenshot.
From my PlayerCharacter, I run the event by pressing 7 on keyboard. The MediaSource dropdown has MediaSource1 selected to be played. But when I press 7, it continues to play the same MediaSource (so will not play MediaSource1 that was selected in the dropdown) regardless of what variable I select in my dropdown.
What could this possibly be ?
