  Rendering alpha, keeping the background?

  Posted by David Sandberg on October 5, 2007 at 11:51 am

  Hey guys,

  I’m rendering out a png-sequence with an alpha channel. The thing is that I want the background layer in my comp to be visible at the edges of the alpha, you know what I mean? I don’t want to remove my background layer an render out to, say, a grey background, I want my background layer to stay in the comp but be transparent except at the edges. Is there any way to do this?

  Render an image sequence with a straight alpha channel and use TIFF or PICT

  Well, it’s been about a year since I started this topic and I still haven’t figured it out. Does anybody know?? Greatly appreciate any help!
