Quote - Thanks takezo3001, I'm trying to recreate that screenshot now.  What image is plugged into the Image_Map_2 node, is it he same as Image_Map_1?

Sorry for the delayed "RE" In the second Image map node I used a bump-map. As far as bump maps go, If you DL a texture set that doesn't have a Bump map with it, You can also make your own, and you don't even need Photo Shop!

Just use Infranview, or Xnview  to desaturate, and invert your picture!

In case you don't have it here's the links!
