In this tutorial, Nick Campell from Greyscalegorilla shows how he uses CINEWARE proxy in his work.

Having a live link to Cinema 4D using Cineware is really amazing. After Effects tries to intelligently cache your renders and does a pretty good job. But sometimes, it will re-render your Cineware layer when you don’t want it to. Cineware proxy changes this. This new script allows YOU to have control over when Cineware updates. Not AE.
