Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and 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. It is available as a standalone renderer on Linux, Windows and Mac OS X, and is accessible through plug-ins for Maya, Softimage, Houdini and Katana.
In general, Arnold is going to work on pretty much any 64-bit system where Houdini, Maya, Cinema 4D, 3ds Max, Katana, or Softimage works. However, there are some minimum OS requirements:
OSX 10.8 or later
Windows 7 or later, with the Visual Studio 2015 redistributable
Linux with at least glibc 2.12 and libstdc++ 3.4.13 (gcc 4.4.7). This is equivalent to RHEL/CentOS 6
CPUs need to support the SSE4.1 instruction set
