I was eventually able to find my objects – I think I couldnt see them because they were “off-screen” as it were. I am using the Motion camera for this project, so it is a little confusing to locate things. I cannot find any easy way to move my view around inside ProAnimator to find my objects.
What I did to eventually get my objects into view was to drag the layer with my ProAnimator project all the way to the top of the Motion project. Im not sure why this worked, but it seemed to do the trick.
