Once you got them all selected, rightclick=> Merge layers
After that, I need to do some small cloning work; as you might have seen there was still a sharp edge in between some of the copyies.
Using a smaller brush size and being more carefull I got rid of them.
Where nearly done with the preparation work, now put "off" your top layer:
1) Click on the small eye icon, to put if on/off
2) Ctrl click on the small image to make/take a seceltion of that layer
3) Go to the second layer, then hit delete
Its time to put away those guides, go to view=> Clear guides.
Put "on" the top layer again.
Time for those blending options, right click on the second layer.
A new window comes up; look for the tab named Bevel&Emboss.
You can follow my options, but feel free to play around with the buttons & sliders, see what they do.
Look for this other tab, named: Innershadow.
Again, play around with the options.
When happy just hit OK to apply those options, you can always go back and change them.
By rightclicking or just double clicking on the layer.
After that, go to the top layer, rightclick and go the blending options.
Under Bevel&Emboss you'll see Contour, go there and play around
Thats it for this tip. If you want to use it, just merge all the layers and save as a TGA/ Targa, 32bit.
EDIT: Added some examples; most left is the texture of that red Sith Quarren.
The blending options is has been used to make his the tabbard, I just made one element, then copied that.
I used it aswell on the edge for his black cloth and on the lines on his shoulderpad.
Center is a floor texture again. Its just used to make the red pop out more.
To the right is a weapons texture, used blending for an extra detail in the blade, on the main body, just to add some plates.
Just a bit everywhere really, to add some details.
