3D Metallic Text

This effect is actually just a variation on the gold text. As you can see below, we’ve again used the dual copies of the text, each with layer styles applied. Here I used a different Gloss Contour on the beveled text below, and of course everywhere we used a yellow shade in the last effect, I used a grey color here.

To try something slightly different, I also applied a text warp. You can do this by clicking on to the text layer, selecting the Horizontal Type Tool (T) and then an icon appears at the top (shown below) that you click on. This gives the Warp Text dialog box.
Now if you apply a Bulge to one of the layers, but not the other, you get a slight distortion that looks neat.
