From My character BP when I want to fade out the widget I get the widget reference, I get the fade out animation, try to play it, then try to remove the widget from the parent.
@thanks to @Shunitzo who got me thinking. I actually don’t know the subtle difference that made this work. I think it had something to do with gating widget actions behind DoOnce flow control nodes. It is possible that the FadeOut was actually working, but there were multiple copies of the widget visible. Regardless, here is the full BP’s that ended working for those who come across this in the future:
I never actually use a “Remove from Parent” node, since this “mini map” widget is called so often. For full context - this widget is being displayed when the “Lander” get close to the ground for a landing view. “Close to the ground” is determined by a line trace.
