Hello! I do not have much experience with Keyshot, so I wanted to participate in this competition to take the opportunity and learn more about this amazing software.
This scene was created in Maya 2017, in fact, all objects that were made in 3D.
The materials used are some of the new metals which is what predominates, and metallic paint.
Nice start! Welcome to the forum. I like the subject matter!
Welcome! Awesome that this is all geometry. Well done - you're off to a great start!
