Just trying out if Avenue might help me to do some realtime-keying in order to get 3 videostreams prekeyed into Unity.
I have 3 video-inputs on separate layers, each positioned besides the other. In Advanced output, I have created 3 screens, with spout outputs and positioned the slices coresponding to the 3 video-images.
If I bypass all but one layer, I get a spout in Unity with alpha, but as soon as I enable a second: the alpha appears to be disabled and all video-inputs show on a black background.
I think I'm overlooking something simple here, any clues?
