Tylor,
Thank you for the reply. What I am trying to achieve is to integrate AE in numerous script and action workflow that I have with Photoshop and Illustrator files. I use Illustrator multiple art-boards and their PDF-counterpart multipage PDF heavily, on Photoshop side – I use nested and layered Smart Objects. Turning Illustrator and Photoshop layers into sequences is kind of basic AE thing that I am familiar with, but the above formats seem to be needed to be converted into individual files before AE can use them as sequences and that is a bit inconvenient. Just imagine dropping in PDF file and animating the pages – but that does not work. I was hoping that I was missing something.
