This was a leaf generator made within Substance Designer that allows a lot of variety within the packages. Things included are number of veins, leaf shape, how much they can effect the edges of the leaf and deform, general aging, patched aging, holes, brown autumn leaf, and custom color. Overall I'm very happy with how it turned out and am excited for my next project.
Dirt texture in render was made by Rob Tuytel and utilized not for monetary gain but for providing a good background for my leaves
