3D MODEL INFO
The model was created based on photos and historical documentation. It was created with precision in detail and in real units of measurement to be a faithful digital reproduction of the original. The object has been modeled in Lightwave and finished and texturized in 3DCoat.
LIGHTWAVE and BLENDER - The engine is assembled with instanced copies of the cylinder to make the entire model lighter.
OBJ and FBX - I provide the entire model assembled as one mesh, but also divided into single parts (base, front cylinder, rear cylinder, propeller) so you can assemble the engine using linked (or instanced) copies to save memory (each cylinder have to be duplicated and rotated around the engine center of 51.43º - 7 cylinders on each line, 14 cylinders in total)
The entire model has 480K polygons, but the single cylinder has 28K polygons only
