Using the below BluePrint, I am placing this widget at mouse location, and expect the circle to be centered around the mouse. However the mouse represents upper left part of circle. How to center the circle where mouse is ?
Make sure your anchor settings are like mine. Anchoring is a canvas-only features and serves a different purpose. It allows you set relative offsets. But it does work here due to its versatility.
Do note that when you add a widget to the viewport, you do so with its upper left corner in mind.
