I’m having a problem here. Help please 
I’m trying to add a background image to the DialogueButtons that comes with the plugin. I set the images on the QuestionsSlot button’s child. Then I have a “problem”, because I want the buttons to expand and fill the full container, so if there is just 1, it will fill the entire container (by default an Scroll Box). You can’t fill a Scroll Box by definition, so I changed it for an HorizontalBox, which allows childs to fill the parent. Nice, should work, right? Well, on the UMG Editor it fills the whole container, but when I hit Play and show one question, it just sets to a default value. Here are the screens showing how it seems hitting Play and the hierarchy in UMG:
What could I do? I need to set a minimum size for every question, or at least be capable of filling my container…
edit: I’m completely sure that is a QuestionsSlot management problem, because I can do what I want (fill, for example) with the same widget structure but not calling the container QuestionsSlot, so the problem lays on the Behavior tree nodes Show Phrases or Wait for an answer. Any clue of what may be the problem?
