If an icon for an asset is missing, a triangle with an exclamation point (“!”) surrounded by a frame appears and signals that the image for that asset's icon could not be found on disk. This Notice appears in the center of where the icon would normally be. When the file for an asset is missing, a notice will appear in the lower left corner of where the icon would normally be. In the event that both the icon and the file are missing, both notices will appear.
