This shot was made in one week. The model of the frog is from one of my previous projects: Project Q.
On this one week project I had to film a sequence and integrate a 3D character in the filmed sequence. I did this by using Maya Motion Tracker to transform the flat picture into a 3D point cloud that could tell me how far away the filmed objects were from the reel life camera.
Then I recreated the church in Maya as a basic model. The animation took me about four hours to make.
I hope you like the result ^^
