Hi All,

I am rendering an image in cycles using render layers so I can apply some compositing effects selectively, but every render layer's Alpha is just pure white. Is there a trick to getting the Alpha to work? Do I need to check something special somewhere before rending? I watched a bunch of tutorials on this and no one seems to be doing anything that I can see - the alpha for that layer just automatically comes out as a black and white mask of everything on that layer and I am getting really frustrated with it.

Thanks for any help, Mark
