1. Re: How to use multiple alpha channels
Mylenium Feb 28, 2008 2:25 AM (in response to Navarro Parker)>Is there a way to read extra alpha channels?
Only via Photoshop batch processing. If you can afford it, simply re-render with the multilayer file option unchecked. Other than that there is no way for AE to see additional custom channels in PSD files.

IIRC, the conversation was enlightening for several of us old timers who had never even heard of multiple alphas.
Closest I've ever gotten was using the four separate color channels to hold unrelated grayscale movies. Each was used to drive a different 3d parameter of Card Dance.
