I have nearly completed this tutorial http://ae.tutsplus.com/tutorials/vfx/create-a-breathtakingly-awesome-rain-scene-day-2/ (press play on preview and it is the first two captions that appear)
But I am wanting to know how to create the text effect to the intro "drops like teras" and "heaven touches me"
It looks awesome.
You can easily create a gradient fill for a text layer by simply placing a solid with Ramp applied below the text layer then making the text layer an alpha matte for the ramp layer.
The wipe can either be done with a animated ramp as a luma track matte or a linear wipe effect.
Thank you Rick.
