uGUI,How to make Scroll Rect backgroudn Transparent?

When I use Scroll Rect,I have to attach an image to use the MASK。 I want to use a transparent background, but I didn’t find a way to accomplish it. Plz help,thx.

Think you are looking for the show mask graphic check mark.

  • you add an image to define the mask.
  • then add the mask . (Uncheck show mask graphic)
