In this video, I’m going to 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.
If you have any comments or questions you can leave them below!
