This is how I approached creating "Ultimate Trim" materials for a Ratchet and Clank fan art project. This was a project I worked on during a mentorship with Ryan Benno, currently a Senior Environment Artist at Insomniac Games. https://gumroad.com/ryan_benno
The original designs for these trim materials were created by Insomniac Games for Ratchet and Clank on the PS4 and are not my own.
