Hi, I want to make an effect where all of the objects and everything fade out to 0% opacity when at the edge of the screen, (like a vignette but it wouldn't fade to black) but I don't know how to do this while keeping the background un-affected without opacity vignette.
Here is an example i'm looking for. The rainbow clouds being the background, and the black being the objects and you can see them fade as they get closer to the edge.
