These Sci Fi pistols were initially based on the following concept art by E N https://www.artstation.com/artwork/6aX1qN. I then took some artistic liberty and altered the design of the weapon and created my own custom color schemes. I wanted to make a firearm that was obviously Sci Fi/future but could be perceived as functional and realistic by modern standards.
I created the pistol, magazine and bullets with Maya and then baked and textured them using Adobe Substance Painter. I rendered all the images using Arnold in Maya with a single Skydome light.
