Is it possible to do what I have depicted in the image attached in After effects? Its seems like a simple thing but I have tried and cannot seem to figure out how this is done. I understand how to use the compositing tag to extract a solid but how do I use a shape layer and how do I place the shape layer between my two cubes? If this is possible can someone please explain to me in steps how to go about this.
Cineware does not interact with AE layers. You simply use multiple layers and stack them accordingly. Any masking can be achieved using the 3D rendered Alpha or specific buffers (object buffer etc.).
