Hi guys, I've searched the tutorials, but can't seem to find the answer I'm looking for. I was wondering if someone could explain to me how to give text a faded look? The effect would be similar to what is seen on most t-shirts today (such as aeropostale, etc.) with white text that looks faded onto a darker backround. Any help would be greatly appreciated. Thanks in Advance, All Purpose
