I'm working on a short with a CGI robot. I found this: https://www.youtube.com/watch?v=RUmamyB-C6o
I'm trying to achieve a similar look with the scratches. The node setup he has in the video, looks quiet complex and I'm not sure how to go about doing this.
Is the best approach to add metal scratches is to create a UV map, that I can add to the metal, sort of like what I did on the face? Is there a different approach?
