there is a template that has a text lighting effect in it. While I undertand how to use masking and so forth, I cannot seem to get this effect. I know Kirupa has a tutorial for this, but it shows a text that is kind of in the dark and the light makes it show up. Can someone show me how to achieve the effect shown in the link. Thanks so much.
