Was there some horrible issue that stopped this feature from ever actually working or did no one get to it? Is it a way serious problem? Most solutions I've seen seem pretty dreadful for situations where you have lots of parallax with lots of different objects.
I'm expecting the answer to be "Not going to happen" but who knows, figure I'll throw this out there. I know C1 development is pretty dead, but this is driving me nuts.
(alternatively, an option to base parallax on screen center might be wonderful instead but whatever)
edit: .... Idea springs to mind to use offset layer effect. Will be back.
