I added background images and now I removed them... But it is not getting deleted from atlases when I optimise and tool>remove unused image objects... Nothing removes it... When I try to remove from atlas by clickking it and pressing delete it says cannot be deleted being used by some objects.... The only thing I used it for was Background and I removed that.... Now why isn't it removing...???.. Same case with some other images in it... Any solution? @jcalle @Christoph @trudnai... Sorry guys if I am disturbing a lot... Thanks for everything..
