Bark Material

I made this bark material for my Oak Tree project. I wanted this material to be quite realistic, and to achieve that, I blended patterns varying in sharpness, size and contrast. I also used Directional Warp and Slope Blur Grayscale nodes multiple times throughout the whole graph, so the shapes would bend and flow together.
I set up the material in Unreal in a way that allows me to control the lichen placement very easily, using both height lerp and vertex paint.
