This was my final in a shake compositing class from a few years ago. Unfortunate my footage was bad, so the green screen key was a big challenge - ended up doing a lot of unnecessary roto. I also had to recreate the shadow cast on the wall also. I reshot myself on location and extracted the shadow that way. I guess I was half successful at that. The floor crack, anvil, debris, and smoke simulation was all done with Houdini Rigid Bodies.
