Arnold was the primary renderer on dozens of films from Monster House and Cloudy with a Chance of Meatballs to Pacific Rim and Gravity. It is available as a standalone renderer on Linux, Windows and Mac OS X, with plug-ins for Maya, 3ds Max, Houdini, Cinema 4D, Katana and Softimage.
Arnold is a fast, memory efficient and scalable physically-based raytracer. Its aim is to simplify the pipeline of VFX and animation companies with a reduced set of user interface elements, and by promoting a single pass approach removing all the associated storage and management costs.
