Unreal Engine 4 is very impressive in its set of 3D skills and toolsets but I am completely in the dark how I would implement a “Drawing-Interface” for the user, e.g. a UI where the user can draw primitives and edit them.
Question 1.) How would I get a 2D-Interface with the ability of drawing lines on it?
Question 2.) How does one draw dynamic lines? Like when the user want’s to draw a circle and resizes the circle or flattens it etc. Thus it seems like every programm on earth uses such toolsets of dynamic sprites I nowhere found any inspiration on how to solve / implement it myself
