Hello Nuke, I need to do something extremely simple, and am running into difficulty. I just want to create an alpha channel from an rgb, where the alpha is 1 where the rgb exactly matches (within some tiny precision) a target color, and the alpha is 0 where the rgb is other.
I tried doing this with an Expression node, and it works, but sometimes the resulting alpha channel is offset in space (but not always). The expression that I'm using is: (r==targetColor.r && g==targetColor.g && b==targetColor.b) ? 1 : 0 where targetColor is a user variable. Is there some easier way to do this? This seems like a pretty basic color-key operation, I feel like I'm solving it the hard way. Chris -- I think this situation absolutely requires that a really futile and stupid gesture be done on somebody's part. And we're just the guys to do it.
