Arnold is an advanced Monte Carlo ray tracing renderer designed from the ground up to efficiently process the complex geometric datasets required for feature-length CGI animation and big-budget visual effects.
Originally co-developed with Sony Pictures Imageworks and now their main renderer, Arnold is used at over 300 studios worldwide including ILM, Framestore, MPC, The Mill and Digic Pictures. Arnold was the primary renderer on dozens of films from Monster House and Cloudy with a Chance of Meatballs to Pacific Rim and Gravity.
Arnold is available as a standalone renderer on Linux, Windows and Mac OS X, with supported plug-ins for Maya, 3ds Max, Houdini, Cinema 4D, and Katana. It is the built-in interactive renderer for Maya and 3ds Max.
