Liberator Mk3 Shotgun Prototype

This is a rendition of a historically fascinating prototype quad barrel shotgun- the Winchester Liberator Mk3. I came across this oddity on Forgotten Weapons, and fell for its retro-futuristic yet utilitarian appeal. It's appearance would fit right in a Fallout game.

Modelled in CAD using Fusion 360, retopo and UV unwrapping in Blender down to a 41k tri first-person model, baking in Marmoset Toolbag 4, PBR texturing in Substance Painter, and final renders again in Marmoset with raytracing enabled.
