@smurfmier1985 Exactly, the Voronoi was the base pattern. Then I added some distress and chaos to the splotches. The shader network loved the pattern and I was able to isolate the center of the blade with a separate material like in the live stream. I then tinkered with the colors, metalness, and roughness values for the outer blade and inner part. It has been a fun lesson. I even added Freestyle lines to one of the renders.
