I've been wanting this enhanced 3D workflow for a long time. To have AE control the same way as a 3D program. A great addition to make this a complete 3D workflow is to have FBX and Alembic support for cameras, lights, and nulls. It would be great to export my animated cameras, lights, nulls and any 3D layers easily and intuitivly into any 3D application, ie. Maya, 3Ds Max, Blender, Houdini, Unreal. Same goes for the reverse, I would like to easily export cameras, lights, locators (Maya Nulls), Empty Plain Axis (Blender's Null) as FBX or Alembic and import them into After Effects. I know AE has great integration when it comes to C4D but this addition can bridge the gap between many different pipelines. In my day to day I work across multiple 3D programs and each requiring different workflows to integrate AE. Ease of use 3d-2d integration would be a welcoming addition to the Animation industry.
In the meanwhile we have the Autodesk "Live link to Adobe After Effects"
Yeah! I love that feature and use it every day!
