I've been trying for days to figure out how to import c4d into after effects appropriately. I have an animation with several PLANE objects and an external composite tag on each. I have turned them into solids, but when I import them into after effects the orientation of the solids are all wrong (e.g. planes with Y orientation get flipped in the Z or X direction). When I do it via Cineware 'extract data' i have the same issue. I attached an example.
We can't know. You have not provided any system info, version info, details about your C4D scene, camera settings and whatnot.
