Ok, so I’m trying to learn how to do green screen stuff basically. So the first step in this was to learn how to remove green from an image. I sorta have that working but am running into a snag. There is a green border that remains around everything after I removed the green. Why is this happening?
And yes I know in this particular image it would be easier to go into photoshop and remove the green or just render the sky with alpha 0 but thats not the point.
Attached is my node setup and the resulting image
