| This tutorial explains how to
create one big scratch for your interface. One might say that
using the
Damages tutorial you can do the same, but if you want a
really big and deep scratch, this tutorial is the best.
To complete this tutorial you will need a background texture ready. Please, note that the result will be better for more solid textures. |
Create a new layer. Set foreground color to white. Using the Paintbrush¹ tool and a small brush (3-5 pixels) draw a rough line which will define the scratch.

Apply Motion Blur filter (Filter > Blur > Motion Blur) to the layer with the scratch. Adjust Angle to match the angle of your line and Distance so the line will be stretched twice its length.
Apply Unsharp Mask filter (Filter > Sharpen > Unsharp Mask). Adjust the values so the scratch will become sharper.
| Set the Blending Mode of the
scratch layer to Overlay.
Duplicate that layer². Set the Blending Mode of the new
layer to Mutiply and its Opacity to 80%. Offset it right and top
5-7 pixels.
This will create an illusion of depth. |
