Laser gun mesh made in Blender(Cycles) v2.79bthe textures are mostly procedural which gives you full controll of scratches or the color.Everything is rigged to an empty. The battery is removable for reloading animationsThe fans on the side are also rigged to a separate empty to make animations of them easier
If you see the scratches and smudges you allready can tell that this Laser Gun went trough alot.It is still completely funcional for killing demons or that massive tank your neighboor is driving.If you use it for hunting you dont even need to grill the meat anymore.
