Searching for Material

Hey everyone, I’m beginning the level design for my first video game, I was wondering if anybody knew of a material to use that is similar to the “graph looking material” Playtonic used for the Toybox in Yooka-Laylee (below). I would greatly appreciate any help in finding something similiar to use, or learning how to make it. Thankyou!

Well, this material should not be any hard to replicate. Just use flat color for base color, and roughness of around 0.8
