C4D r13: Native scene file, you will get the render preview if you simply open this file in r13 and click render. The camera, DOF, and Sub-surface scattering shader are all features of the new Physical Renderer in C4D r13, so they are not compatible with r12, and although the file is compatible with r12, I recommend you use the r12 file I included.
C4D r12: The same scene and camera settings as the r13 file, but the materials do not have the new SSS shader and are translated just using a color layer.
.3ds The same scene and camera, but limited materials that may or may not be linked to the textures correctly depending on if you open them in C4D or another program.
.obj: Just the scene/models, no camera or textures.
