So I've got two qt's or tiffs with alpha channels. And I want to use the alpha channels as clipping maps for videoplanes.
So I have transparent areas of one video plane that show the the other videoplane or background playing behind it.
I know I have to use the blend_mode attribute but I'm obviously missing something.
Can someone point out the obvious to me?
The patch is setup to accept two tiffs or qts with alpha channels.
