| Inline 4-cylinder (I4) internal combustion engine modeled in Carrara 4.0 and provided in .car, .3ds, and .obj formats. Model includes pistons, piston rings, piston pins, connection rod, bolts, and crank shaft. Bolts and bolt holes feature simplified 3D threads. Assembly can be broken down into its individual components. 'Cast iron' and 'machined' surfaces are broken apart to allow quick texturing without having to deal with UV mapping. Works in all major 3D programs. Provided in three formats. Uses basic shaders. No textures needed. No plug-ins required. |
