Tried the new free Star Wars pack from video Copilot. Only used the X-wing and Tie fighter. You can download it from the link below. You need Element 3D for After Effects installed of course.
You can see some flickering going on in places, that using Element 3D Ray tracer, haven't found the solution yet.
