Hi All -
I know this is a much-discussed topic - but after reading some of the previous discussions, I'm still a bit confused..
I've attached a patch that has two GL sections - one is just a qt.movie into a chromakey slab and the other is an isosurf in a chromakey feedback arrangement.
They are mixed together via an xfade slab.
What I would like is for the isosurf feedback to crisply overlap the background image, without blending and whitening the image.
I realize that another chromakey slab could remove the white background from the feedback channel and impose the video, but this potentially creates different kinds of sloppiness - especially if I decide to change the color of the isosurf or the feedback starts to get heavy.
Is there a better way to do this?
