Spent a little time playing around with the granite texture today. The glossiness didn't really show well here, but the patterning is fantastic!
On the left is the original granite texture, and on the right is the one I created today. There's 2 layers of "marble" texturing and 3 layers of voronoi to wind up with the look. Then a little RGB curves to bring the color contrast back up because it was getting a little dark.
The environment here doesn't show off the glossy as well as another I have, but you can see the striping. If you look in the ear, you can see a reddish vein, and across the nose is the darker vein.
