repo alpha?

[Brian Berneker]

Create a new solid just beneath the layer with an alpha channel and set the layer mask to point to the alpha for that layer. It will turn your solid into a cutout.

If you need it to be a B/W mask, you can do the whole thing inside a pre-comp, make the solid white, and create an additional black solid beneath it, so that the transparent areas show through as black.

I’m not sure, but there might even be a simple filter (i.e. levels etc) that lets you show the alpha channel directly with the channel pulldown.

well, I am trying to make an efficient, easy fx favorite that will do this along with other things to give a certain look.
That would rule out the dup’ing of layers to use as the matte.

any effect do this?
