Mad Max's Double-Barrel Shotgun

This is a recreation of Mad Max's trusty 12ga double-barrel shotgun. I tried to get very close to the actual weapon from the film "The Road Warrior", although, there are a few inconsistencies. But what's a Mad Max film without a few inconsistencies here and there. I made the 12ga shell a slug round because there is a scene near the end of "Road Warrior" where Max uses the shell he scavenged for a long-range shotgun shot towards Lord Humungus. The shell turns out to be a dud, but I'm using this to determine this long-range attempt as evidence Max knew it was a slug round. It's a small thing, but it's fun detail. Each moveable part is modeled separately for animation possibilities. Modeled in 3ds Max and textured in Substance Painter. And as you can see, I tested a couple of different renderers and techniques to help me learn more about rendering. Thanks for viewing!
