How to create a shadow gradient for a rectangle in PSD like this one?

Question

I would like to create something like this in Photoshop. Any hints? :)

Answer 1

1. Create a rectangle shape layer, duplicate it, move it down and to the left.
2. Select the bottom shape layer. Add an anchor point, convert it to a corner point.
3. Click and drag the points to make the back shape.
4. Add a gradient fill, and adjust the angle.

Answer 2

For multi-gradient shapes you will need to use multiple gradient layers.

So have your foreground rectangle on the top layer.

Have the horizontal gradient at the bottom.

Place the vertical gradient in the middle and use a layer mask to hide the left side of the layer to show the gradient layer below it.
