3d models of all the parts of a 9 cylinder piston mechanism. All the parts were made with subdivisions and almost all have low rectangle count (except gears). All the materials are procedural and PBR. These files do not include the outer motor chamber and is not animated. For the chamber, propeller and plane nose see: https://www.cgtrader.com/3d-models/aircraft/part/radial-aircraft-motor-with-propeller-and-plane-nose. Finally I animated all the parts working together with a rig for this package that includes all 3d models, rig, materials, and animation see: https://www.cgtrader.com/3d-models/aircraft/part/radial-motor-with-piston-mechanism-nose-propellers-anim-and-rig.
