Here is a test I have done for implementing 3D into a live action plate: http://vimeo.com/7594029 http://vimeo.com/7942110 It started in 2009, in the time a had between projects at the company I was working for. I finished it 6 months later after I left the company to work as a freelance compositor. The modeling is done in Cinema 4D, the texturing in Maya, the animation, shading, lighting and rendering in Houdini HD and the compositing in Shake and Nuke.
