I've just recently switched over to CC from CS6, my thinking was "if it ain't broke, don't fix it". But clients are living in a CC world, so now I have to deal with it.
I've got all my null layers tracking some footage and it's all visible, so that's fine. But if I want to play and watch my nulls move about the screen, they all disappear until I press the space bar to pause. Scrubbing through the timeline manually does not cause the paths/nulls to disappear. Below is what it looks like after I try to preview by pressing the Space Bar.
I loved the functionality of seeing where my layers' anchor points were while playing and it's important to my workflow. Is there a way to turn that on again?
the preview panel has changed in CC2015 and offers you the flexibility to choose what you want to see, and how you want it to behave in a great extent. just suit it to your needs.
