Another procedural wood. I made the veins more grainy, and I added distressing. The 'Distress' parameter should look best between 0 and 1, but if you want to go higher you will get bigger marks. I wouldn't go above 5 because it starts to look weird. There is also better control of the positioning of the wood grain.
