Hey there thank you for the response - what sample for the animations are you using?
what each transition is: Normal is the blank animation highlighted is the 4 animation frames pressed is (i will just go 1 frame backwards) selected is im unsure?
I have gotten further with it. I cant resize the images with preserve aspect on as its required to get the thin white bar to have that overstretch effect. If you have a unity example that would be greatly appreciated all goods otherwise
