In order to create this diploma paper, it was necessary to bring together a small team in which each person has a specific task in order to create a quality product in 3D animated technique. The initial steps for making a movie were: form a story, write a screenplay, design characters and make a storyboard. After that, I modeled 3D objects such as the characters themselves for the animated film and the scenario in which the film's action takes place. After that comes texturing that adds to the final atmosphere. After modeling, I animated in Autodesk Maya. This was followed by lighting and additional animation of 2D elements in other programs. The next to the last process is compositing, the last being the rendering and editing of video and audio. The movie I made shows little creatures that enter a human body through a foot that is like a factory. Their main task is to clean up all the clutter inside a foot so that the person could start a new working day with rested feet.
