I'm not having a problem with R16 or R17 exporting correct camera data to After Effects. I wonder if there's a preference setting that's gone awry in your C4D that isn't set up that way in your old version.
If the camera move is linear its fine, add a curve and it goes out of sync. This is happening at two locations with different studios. This has been an issue on and off since R13 and the old ace import which works fine.
Did anyone get an answer to this?!
The only workaround i have at the moment is to bake every conceivable piece of animation in my scene and then use cineware to bring in the data as usual. Not ideal in a giant project at all.
Martin, did you have any issues with opening up an R17 file in R13?
