I'm wanting to import a CS3 Indesign file into a CS3 After Effects file including all the layers. Is there a simpler way than importing it into Illustrator then dividing the layers then importing into After Effects?
Nope, not that I'm aware. Unfortunately AE does flatten layered PDFs, so that second option wouldn't work, either. It should however be possible to spit out each layer as a separate PDF from InDesign with a little work. Perhaps even someone already has created an extension/ command set for this, so I'd ask on the ID forums.
