Space probe Dawn currently heading to the proto-planet Vesta and the dwarf planet Ceres. Created in 3Ds Max, as two seperate meshes, the main probe body and the solar array, both with own texture maps, the array can rotate and intersects the main probe body via a tube so both meshes remain fully enclosed with no open edges.
