All the production was carried out with 3ds Max. Manuel Alligné spent a lot of time developing a rig for the main character. This saved a mass of time in working and reworking the scenes. “We worked with mental ray for a simple reason that it was imposed by the school as the render engine,” says Weibel. “No problem though. We had an excellent teacher that learned us how to get nice images and how to avoid the commonly feared effect of flickering!” A simple tool was devised in maxscript to improve the entire workflow. It mainly allowed the team to automatically create ambient occlusion, z-depth, object ID and alpha passes, and quickly set a job for network rendering with Backburner which was a good way to speed up the render setup.
