AMD ships Radeon ProRender 2.5 for Blender in beta

Monday, August 24, 2020 | Written by Jim Thacker

AMD has released Radeon ProRender 2.5 for Blender, the latest update to the Blender edition of its free, physically accurate GPU renderer in beta.

The release updates the new next generation rendering mode based on version 2.0 of the Radeon ProRender SDK and makes it available for viewport rendering and final quality output.

Other changes include an interesting new option for samples per second, which AMD describes as analogous to a target frame rate for rendering viewports, as well as support for the upcoming Blender 2.90.

The new next generation rendering mode based on Radeon ProRender 2.0 is now available for rendering viewports
In the previous version of the plugin, AMD introduced an experimental rendering mode based on version 2.0 of the Radeon ProRender SDK that improves performance when rendering with multiple GPUs or CPU and GPU.

Version 2.5 extends the new mode and makes it available for both rendering viewports and final output.

AMD also says that when rendering in RPR 2.0 mode, the noise should be lower for a given number of samples and the rendering speed should scale better across multiple GPUs.

Other new features in the Radeon ProRender 2.0 SDK itself, which were also updated this week, include support for Light Path Expressions, the MaterialX open standard for material data, and new spherical and plate light types.

The New Samples Per Second option maintains a constant frame rate for rendering viewports
Radeon ProRender 2.5 for Blender also offers an exciting new option for viewport rendering, which AMD describes as "roughly analogous" to a target frame rate.

When this option is checked, Radeon ProRender will automatically adjust the viewport rendering resolution to maintain the sample rate. In this way, the interactivity is retained in complex scenes by exchanging it for the rendering quality.

AMD describes it as "a much better viewport experience, especially with higher resolution displays".

Other changes include the option to import sequences from OpenVDB volumes or import animated textures as image sequences, as well as support for the upcoming Blender 2.90, which is slated to ship later this week.

There are also some minor performance and workflow improvements: a full list can be found via the link below.

Availability and system requirements
Radeon ProRender 2.5.1 for Blender is currently in beta.

The current stable build, version 2.4, is compatible with Blender 2.80+ on Windows 10, Ubuntu 16.04.3 and 18.04.0 Linux as well as macOS 10.13.3+ and macOS 10.14. It's a free download.
