i need it on everything. as it is now, everything in the background must be touching something else in a long chain in order to hide the different long depths. i have to hack things to try and get them to appear as if they don't have these long backs. if you want 3d separation (z-scale difference), you have to make these long depths on the back of sprites. not very attraction most of the time. it would allow free floating things in the background/foreground.
