Arnold from Autodesk is an advanced unbiased Monte Carlo ray tracing renderer. It uses the power of your CPU to calculate illumination in the scenes by default. You can, however, switch between CPU and GPU rendering depending on your needs. Arnold is famous for its staggering hyperrealistic renders, which is why it’s perfect for creating cinematic shots. When you have a massive amount of fine detail in your scene, when you’re dealing with intricate textures, or when your lighting setup is complex, a precise renderer like Arnold will ensure that none of your hard work goes unnoticed. Think of the stunning visuals of Blade Runner 2049, Guardians of the Galaxy, or Tim Burton’s Alice in Wonderland – all three were rendered using Arnold.
Arnold for Houdini (HtoA) provides a bridge to the Arnold renderer from within the standard Houdini interface. Having been in beta for several months, the plugin has already been used in production by many studios, including Prime Focus World for Hercules and Vampire Academy, Milk VFX for the Sherlock and Doctor Who TV series, and Framestore NY for the Captain Morgan commercials.
