I liked the picture from Lapo Roccella Flying Scooter - https://www.artstation.com/artwork/oZ0mq.
I wanted to recreate the power/fuel filling unit for the scooter as a challenge for my self , 90 % of the materials created where done in 3ds max with only a few black & white jpg where created in Photoshop to be used as cut out and bump map , I used a lot of composite , coulour correction and out put where used. The pipes textures which I'm relay happy with I used gradient maps.
