Creating a gradient opacity mask

In this exercise, I'm going to show you how to create the most useful kind of opacity mask there is. That's a gradient opacity mask. I've saved my changes as Conceal & reveal.ai, so called, because we have this square here inside the opacity mask. That's where I'm working right now. So I'm midstream on this project. I've got this square that's set to black, so it's concealing the contents of the layer. I have this circle that's set to white, so it's revealing the contents of the layer. They're both movable by the way. You can move them anywhere you want. They'll continue to conceal and reveal as you go. If you want the opposite behavior, I'll just show you this. You can turn on the Invert Mask check box, which goes ahead and reverses the objects. Not the background, just the object, so that black is now concealing, and white is now revealing. I think that's insane. So I'm going to go ahead and turn that check box back off. But Illustrator is nothing if not flexible. All right, well…
