12 Show material variety
Consider contrasting materials such as fabric with hard surfaces. Use photos to easily sell the illusion of different materials. This adds variety and believability to the piece. Think about shiny and matte surfaces. What kind of pattern does the fabric have? Is the fabric stretchy or is it a hard, rigid material? Thinking about the mech’s purpose can help determine what type of materials should be used. A military mech may need a more armoured surface to protect itself, while a mech that’s required to be more agile may need flexible fabrics for easier manoeuvrability.
