I am making a duplicate of a layer which has layer style effects (drop shadow). Next, I'm changing the angle of the drop shadow on that new layer. However, when I do that, the angle changes on the original layer as well. How can I change the copies' angle to my liking, without affecting the original layer's drop shadow angle?
I have tried copy/pasting the layer, making a duplicate, going with CTRL+J, creating a completely unrelated layer (shape, importing from another document, etc) and it was always the same, as if the drop shadow angle was a global setting.
I know that I could rasterize the original layer, and then change what I need on the copy, but I'd rather keep it as it is.
I'm using Adobe Photoshop CS 6.
