This is an 1855 Colt Revolving shotgun. It boasts a low 7,688 tri count(3,848 quads) and three different 2k texture sets for a nice polished feel. The origin points of the hammer and trigger are all setup and ready for animation in the game engine and the model is a single fbx with a few meshes for extend customizability/animation. All three versions of the shotgun textures are shown in the images. For each set there are three renders taken in substance painter and a single image of the shotgun in the Unity 3D game engine.
