VCL utilized Autodesk FBX data interchange format to exchange data between Maya and 3ds Max. 64-bit Linux-based systems were used for a number of fluid effects and dynamics in the film. The ability to use Maya Embedded Language (MEL) scripting in Maya allowed more advanced artists and technical directors to create a library of effects that could easily be plugged into shots. These presets could then be applied by any of the artists to a variety of objects by calling the script, placing it into the shot and turning around a desired effect within a short timeframe. Working in small teams, VCL had to automate as much as possible — using Maya and a library of scripted presets enabled them to do this very efficiently.
