I painted and rendered the rifle using Substance Painter. I created two textures for the same mesh: Standard Gun and Old Damascus Gun. Also, I did an additional render of the Damascus Gun in different lighting.
This was completed in a class instructed by Christophe Desse and the gun was modelled by Inkyo Lee.
