Changing UI Slider Art

Alright I have no idea on this one. I am using a slider in my game for a menu and obviously I don’t want it to look like the Unity default one. However whenever I try to drop in a new sprite and tell it to be native size it freaks out in play mode and resizes and skews it. Also I need the bar to extend the whole length of the screen and that does the same thing if I tell it to be native size.

Am i doing something wrong? I am able to obviously change the scale of the objects, but that doesn’t result int he crispness of the sprite at native size. Are there some specific steps I should be following?

Thanks

don’t try to use the native size option try customising the scale of both background and fill yourself till you get the shape you want
