"Each shot was like a blank canvas, requiring layer upon layer upon layer," says The Mill's Chief Creative Officer, Pat Joseph. "It's possibly the most demanding project we've ever undertaken." The Mill had to strike a good balance between figurative and realistic in their creation of the cloud gods. To achieve a high degree of realism, CG elements were tracked onto real cloud formations and additional layers of cloud added to enhance them.

This project provided a real learning curve in terms of working practices. Since the job was posted HD, Mill 3D investigated ways of speeding-up render times by using the integration of Maya 6 and Mental Ray for fluids and dynamics. The CG department also implemented a new, streamlined, production-line method of project management. A dedicated cloud website, outlining every setting used, was created purely to see the development of each cloud render and to let everyone involved to track the development of each 3D cloud.
