When I was originally setting up a game, I imported a couple backgrounds. Now that I have the new ones in place, the old ones were deleted from the game field world. I did the "Optimize" and "rebuild" and used all the remove tools in the drop down menu. But the two BGs are still showing up in the atlases. Any suggestions?
Select the image in the atlas (click left on name, not right on picture) then just press delete on keyboard.
@tprobst thanks. I tried that. But I got this message... I went through every page. It is not on any of them. But when I go through the sprite editor (i.e. click on any object in the game field and click the edit button for that object) I see it there in the list of available items to substitute.
If you can't delete it (I've had that problem in early 2.? and send your bbdoc to support and they can remove it. Also check to make sure that it isn't inside of another asset or on one of your UI screens.
