    Full On Alpha Channel - and mask?

    moceandesigns

      I have been rendering pngs out of Lightwave with background imagery in the color channels, and an alpha channel for just the objects.

       

      In my comp I duplicate the footage layer, and then on the bottom layer apply the Shift Channels effect, and set the alpha to Full On so I can see my background.

       

      Now I want to run some masks on my backrground layer, but the Full On Shift Channel ingnores all my masks.

      I can work around it by doing the masks on a new layer above the BG and telling it to take the alpha from that, but I would rather keep things tidy and all on the one layer.

       

      Is there a different way to tell a layer to not use it's built in pixel alpha info, and look at it's masks?
