So, I imported the image as an atlas texture. But if I, say, set the normal image for the button as [1,1,350,50] and then the pressed button as [1,102,350,50] it changes the normal button's image as well. Clearly, I am lacking some understanding of how this works. Can anyone enlighten me? And yeah, I know I'm almost certainly doing this in an over-wrought fashion (just having the buttons as separate image files would work better), but humour me here as I'm interested in learning how this works.
