This has been my second model of my FAB bombset re-creation. This model was created in the Blender 2.79 build. My first set of images are via the Cycles Render method and gray color. (as seen with the noise and color) Here is some information on the bomb itself: The Russian term for general-purpose bomb is fugasnaya aviatsionnaya bomba (FAB) and followed by the bomb's nominal weight in kilograms. Most Russian iron bombs have circular ring airfoils rather than the fins used by Western types.
