The IMAM Ro.43 was an Italian reconnaissance single float seaplane, serving in the Regia Marina between 1935 and 1943.
I made it in Lightwave 3D, then I painted textures in 3D Coat and Blender. The model has a simple setup to animate the moving parts (ailerons, rudder, etc.) and is compatible with Houdini
