In this video, I will show you how to create and animate a “Knockout” layer using the Advance Blending options (above Blend If) in the Layer Style window.
The Knockout blend allows you to turn a layer into something similar to a mask.
This type of layer punches through all the layers below it, and it reveals the bottom-most layer.
Unlike masks, you can apply layer styles to these knockout layers to create more interesting effects.
