Very detailed, animated Tool Box.
Everything is modeled with a lot attention to detail.
The base format is Cinema 4D R12 and it contains the model unconverted using nurbs, hyper-nurbs, etc and also all the shader materials plus light setup and settings used to create the renderings above. The model is also animated and includes opening/closing animations.
all (but 3DS) include the high-res converted model plus the low-poly subdivision mesh for use with your 3D software's subdivision modifier.
FBX and VRML contain the animation as well (on high-res and subdivision version)
all other formats are static but still contain high and sub-d versions.
