So I decided to combine one leather node tree with a metal one, the first image is the result without any editing. With the following images you can see how it slowly changes. As a result of these two surfaces, I have managed to get over 30 surfaces and boy, some are very cool...most were unexpected!
I'm calling the metal extension pack complete...I might release it on Friday or there abouts.
I think those first five surfaces will look good on my sofa model....Mmmmmm :)
