I am trying to highlight a rectangle of arbitrary height. I thought the easiest way to do this would be to create a separate "box" gameobject that outlines the rectangle.
I've tried with both a MeshRenderer + Transparent Texture, and a LineRenderer to outline the four points of the rectangle. Neither are very satisfactory.
(Line renderer on in the middle, scaled cube on the right)
What's the right way to go about this? I am trying to get something like the left rectangle - a simple perimeter of fixed width through four points of my choosing.
