How to set a static background to a bar gauge?

Not sure if I am missing something silly - trying to make a bar gauge with a foreground image (the value) and a background image (the track itself)

I’ve tried playing around with background and mask images, but can’t seem to set a backing image that isn’t affected by the changing values… Any ideas?

Bar Gauge uses a image for the bar itself. To achieve what you are after, use multiple gauges layered on top of each other.
