Step one:
First create a new image and typ your text in it. I used blach but you gan use any color as well. Then Rasterize the layer.

Step two:
Use Edit >>> Transform >>> Perspective to add a dimension to your text.

Step three:
Then press Alt and your arrow keys to copy the layer en move it 1 pixel. If you use this perspective you can use the Left and Down arrow keys. As you can see a lot of layers are created.

Step four:
Now, select the original layer (the one just above the background layer) en hide it as well as the background layer and hit Ctrl + Shift + E to flatten all visible layers. In this case the name of the layer that is created is '3D TEXT copy 21' Now move the flatten layer (3D TEXT copy 21) between the original layer (3D TEXT) and the background layer (Background). And make all invisible layers visible.

Step five:
Now you can hit Ctrl + U to add some color to the text layer. Rember to active colorize in the bottom left corner in the dialogbox. You can color the top layer as wel as the other layers.

Step six:
The final image. If you need help or you have a question drop me a message at
