View Full Version : Assigning Alpha Channels
03 March 2003, 04:56 PM
Hello, I was wondering if there was a way to have a targa sequence that is just RGB's and take a seperate sequence of black and white images and use that as an alpha channel for the RGB sequence. Ive messed around with the "Set Channel" and "Set Matte" option under effects, but I cannot seem to get it to work, any help would be greatly appreciated. Thanks

Track matte is what you want!

As addition to what Opacity says, I'd like to point out that you'll have to choose "Luma matte" from that menu, not "Alpha matte", if you want to use black & white images as an alpha channel.
