Panner/Coordinate texture will not help here.
Image Size inside the Widget does not work.
How can I make the image appear bigger, i.e. overlap the edges of the progress bar so that the part of the image I want to be displayed can fill the progress bar?
I don’t know how ideal it is but I I’ve made the edges of the progressbar a separate image. I then manually resized the actual progressbar until it fit the edges.
I might be able to give you a better solution if you post a picture of what exactly is wrong allong with an example of the texture you use.
