yes, of course! I'll try to explain myself better:
You can add every layer a bunch of effects: drop shadow, inner/outer glow, bevel/emboss, satin... you must know what I'm talking about.
What I intend to do is to cover (hide) some parts of these effects without covering the pixels of the layer they are attached to.
The only way I know to do this, is by converting those effects which are applied to the same layer into different underlying layers which then I can easily mask, but it's an irreversible process. Well, I could duplicate the initial layer including its effects, but,
is there any way to directly mask layer styles/effects??
