The new version of Autodesk’s Arnold introduces Arnold GPU in public beta, giving artists the chance to switch between rendering on the CPU and GPU with a single click without changing renderers.

Based on the NVIDIA OptiX framework and optimized to leverage NVIDIA RTX technology, Arnold GPU is a sign of the changes that more powerful graphics cards bring to the industry. Now unveiled by Autodesk, Arnold 5.3 with Arnold GPU, in public beta, gives artists a first taste of GPU rendering. From look development to lighting, support for GPU acceleration brings greater interactivity and speed to artist workflows, helping reduce iteration and review cycles. Arnold 5.3 also adds new functionality to help maximize performance and give artists more control over their rendering processes, including, says Autodesk, “updates to adaptive sampling, a new version of the Randomwalk SSS mode, and improved Operator UX.”

Arnold GPU rendering makes it easier for artists and small studios to iterate quickly in a fast working environment and scale rendering capacity to accommodate project demands. From within the standard Arnold interface, users can switch between rendering on the CPU and GPU with a single click, and there is no need to change renderers. Arnold GPU currently supports features such as arbitrary shading networks, SSS, hair, atmospherics, instancing, and procedurals.



Arnold GPU and NVIDIA RTX


“We recognize the needs of Arnold users for increased speed and interactivity during the creation process,” said Chris Vienneau, senior director, Media & Entertainment Products, Autodesk. “We’re excited to introduce this beta version of Arnold GPU because it gives our users a first taste of the performance gains they can expect to see, while keeping the great look they love from Arnold. We’ve worked closely with NVIDIA to optimize Arnold GPU to run on the latest RTX technology, and look forward to continuing to collaborate to bring our customers the highest quality rendering.”

“We are thrilled to collaborate with NVIDIA and Autodesk on the next generation of high-performance production rendering. Delivering the best creative results fast is critical to our success,” said Carsten Kolve, digital supervisor at Image Engine. “GPU rendering on NVIDIA RTX Server with Autodesk Arnold promises to deliver the exponential leap in speed we hope to utilize in all production departments.”



Key features of Arnold 5.3


Here is a quick list of some of the key features included in Arnold 5.3:

• Major improvements to quality and performance for adaptive sampling, helping to reduce render times without jeopardizing final image quality
• Improved version of Randomwalk SSS mode for more realistic shading
• Enhanced usability for Standard Surface, giving users more control
• Improvements to the Operator framework, including a new Include operator and more artist-friendly way to apply them
• Better sampling of Skydome lights, reducing direct illumination noise
• Updates to support for MaterialX, allowing users to save a shading network as a MaterialX look

Arnold 5.3 with Arnold GPU in public beta is available from today, March 20, 2019, as a standalone subscription or with a collection of end-to-end creative tools within the Autodesk Media & Entertainment Collection. You can also try Arnold GPU with a free 30-day trial of Arnold. Arnold GPU is available in all supported plug-ins for Autodesk Maya, Autodesk 3ds Max, Houdini, Cinema 4D, and Katana.
