Melt It is a Photoshop action pack that transforms your text (and other layers) into 3D incandescent objects.
There are 3 actions included. The first action produces an intruding (whole in surface) 3D effect. The other two creates extruded 3D objects, with two different look.
Also, the entire colors can be changed! See the previews.

Note: If you have any problems with the look of the result, just load this PAT Pattern file before applying the action.
