Here are the models I created for the Balloon Animatic, as well as the final video (models staged in Unity for video clip). I created the Carousel model in Maya. It is missing the back of its crown to lower the cost of production. I modeled the Ferris wheel procedurally in Houdini Apprentice and converted it into an FBX before bringing it into Unity. Enjoy!
