To make sense of the subject, I have a text logo that I created in illustrator and imported into ProAnimator. I want to add a flat black logo behind it that is 10 px or so bigger. Of course I need it to animate the same as the logo. Does this make sense?
It sounds like you're wanting a black border or edge behind your logo. If you want them to move together, the simplest way is to use an edge that creates this kind of shape or make a custom bevel to do it.
