Joren Kandel from The Pixel Lab has posted a two-part tutorial on getting your Cinema 4D shadows integrated into After Effects. In the first part he talks about bringing your AE background into C4D so that you can have your shadows cast realistically on the right plane.
In part two, Joren tells you how to render your footage, Object Buffers and your Shadow Pass. Finally, he shows you want to do with all those new layers in AE.
