If you get this warning, we recommend resetting After Effects to use the default CINEMA 4D engine until an update for CINEMA 4D R18 with the engine improvements is released, which is expected shortly after the release of After Effects CC 2017. To do this:
- Open the Composition Settings dialog.
- Click on the 3D Renderer tab and choose the CINEMA 4D renderer.
- Cick the Options button.
- Click the Choose Installation
- Click the Defaults button.
Team Projects is a new hosted collaboration service for Creative Cloud for teams and enterprise customers that allows editors and motion graphics artists to work simultaneously in shared projects within the 2017 versions of After Effects, Premiere Pro, and Prelude CC.

For more details, read our announcement about Team Projects.
In After Effects, you can create or open a team project using the File > New > New Team Project (Beta) and File > Open Team Project (Beta) commands, or the equivalent buttons in the Start screen. Use the Edit > Team Project menu to manage an open team project.
