In its blog post, AMD claims that RPR – Interactive is “nearly as interactive as Eevee”, Blender’s real-time render engine, and “close to the lighting quality of Cycles”. Other key changes include support for displacement, and better support for MaterialX: RPR-Interactive supports all of the materials in AMD’s free online MaterialX material library. RPR – Interactive is also now better supported on older GPUs without dedicated ray tracing cores, and cards with less than 8GB of graphics memory.

Interactive rendering now uses the Nvidia-developed global illumination algorithm ReSTIR for direct lighting, and AMD’s own FSR 2 technology for render upscaling. In addition, interactive rendering mode RPR – Interactive – which uses Vulkan rather than HIP or OpenCL – has been updated to brings its output closer to RPR – Final. HIP is now used as the backend for Radeon ProRender’s RPR – Final render mode, although the legacy OpenCL backend is still available for older GPUs.Īlthough the change may result in a “slight performance boost on some cards”, the main reason is the decline of support for OpenCL within CG software development.Īll three plugins: better intective rendering One of those is to switch the API used for final-quality rendering from OpenCL to HIP, AMD’s own open-source technology, also now used in Blender’s own Cycles renderer and Redshift.

The update was released alongside Radeon ProRender 3.4 for Maya and Radeon ProRender 2.4 for Houdini and USD, the latest versions of the Maya and Houdini editions of the renderer.Īll three plugins: final-quality GPU rendering using HIP, not OpenCLĪll three updates implement some of the key changes from Radeon ProRender 3.1, the latest version of the Radeon ProRender SDK, which was released earlier this year. The update switches the software from OpenCL to HIP for final-quality GPU rendering, and improves interactive rendering, adding support for displacement and better real-time GI.

The Blender, Maya and Houdini editions of the free GPU renderer have just switched from OpenCL to HIP for final-quality rendering.ĪMD has released Radeon ProRender 3.6 for Blender, the latest version of its free GPU renderer.
