    How to use multiple alpha channels

    Navarro Parker Level 3
      Hi there. I'm using Cinema4D for some 3D animation. I'm using an object buffer compositing tag to isolate certain elements in my scene. (C4D can create an alpha channel for each object). This is then rendered out as a multi-layered PSD sequence. However C4D puts the extra channel info (z-depth, object ID, etc) into alpha channels. But AFAIK, AE only reads the first alpha channel.

      Is there a way to read extra alpha channels?
