Hi Andreas, I’m actually trying out a similar workflow. Did you figure it out yourself or did you find documentation to work these steps out, I’m currently trying to export an FBX file from the camera directly from after effects with a plugin, and am planning to go back to after effects for the compositing by rendering out my scene with alpha.
If you have more information on the import of the camera, please share, I’m getting strange (read: no) results at the moment.
TX!
