Hard surface modeling is a challenge in any 3D application, especially without blueprints. This was more of a modeling/hard-surface study using box modeling techniques, and workflow optimization with Substance Painter. Anyways, I really like the design of this shotgun, so I went for a realistic style while keeping the model clean as quad-like as possible. Totally "game-ready" as it's fully unwrapped and set up to use PBR textures and materials.
