Hi Matrin, The shape drawable does not store or represent a mesh, rather internally it creates the vertex and primitive data and display lists it for rendering. Given this there isn't anything to export to a format like .obj. Creating conventional meshes is supported though, but .obj is very very crude format so will loose much of OSG state and structure along the way. Exporting to OpenFlight or Collada would probably be a better route.
