Each year Ubisoft holds a company event dedicated to Material Art and our internal library tool, Candyshop. Last year I was invited to give a talk there and Ubisoft has been kind enough to let me share it publicly with the community! The talk details the research I had done into different workflows for creating color and the subsequent nodes that came from this research.
