I have found that filling with 50% gray helps produce a more even rock texture.
Press Shift+Delete (Shift+Backspace on Mac) for the fill dialog. Choose 50% gray for contents. (For a more metallic effect, leave white instead of changing to gray)
Step 5
Filter>Render>Lighting effects.
You will need to experiment with some settings, but here are the essentials
Set light to Infinite
Select Alpha 1 from texture
Choose something for the color, in this case an orange.
Change the height to get more or less texture.
Grab the on-screen widget and drag around for different angles and intensity.
Click ok
Step 6
Instant rock.
Step 7
For some variation: Add a Hue/Saturation adjustment layer
Reduce the saturation for an interesting look
Or turn on the colorize option and try something more colorful
