How to apply a layer style to a group in Photoshop?
I have a collection of shape layers that I'm dividing into four groups, to apply a different layer style to each group. I've read in the online Photoshop User Guide and in a third-party tutorial that layer styles can be applied to a group. However, nowhere can I find an explanation for how to do this.
I tried selecting the name of the group and applying the layer style to it. But it has no effect on the shape layers below it. I've applied the same layer style to individual shape layers, and it works fine, so there's nothing wrong with the layer style.
